For the lazy:* get Premium (50% more XP)
* get a Premium Tank (Tier7 for 20% more or Tier 8 for 10% more XP)
* get the Mentor Skill for your commander (10% more XP according to the PC forum. How much it really is on the xbox is unknown)
For everyone interested in the details:IMPORTANT: it appears that WoT had an issue where Premium & Elite Tank bonus was
NOT applied to CrewXP. See
http://forum-console.worldoftanks.com/index.php?/topic/14877... for details. In such cases, the players were compensated with 6xCrewXP Boost Ops. If you have those, use them as they will greatly help speeding up the process.
You need to get one of your tank crews to level 10. Starting from scratch you need
3,806,745 XP (revealed by WG just recently:
https://console.worldoftanks.com/en/news/community/community...).
The current crew level is displayed since update 3.2 on the main garage screen next to your crew perks (like 9/17, means this crew is level 9 out of possible 17). To see how far into the next level you are, highlight the tank a crew is assigned to in your garage, then press (X) to get to the upgrade screen, and then select Crew (2nd from the left). In the top right corner you will see your crew rank and a somewhat greenish bar which indicates your current progress to the next level.
This is the amount of XP needed to get from one to the next level (those are the most tedious ones):
lvl 8 -> lvl 9: ~ 800,000 XP,
lvl 9 -> lvl 10: ~ 1,600,000 XP
Your crew level increases by XP earned in battles (the total battle XP earned equals the XP for the crew - you see that on the battle result screen). That should not come as a surprise. However, there are a couple of mechanics to remember on how XP is earned and calculated. Most of the information below is gathered from my own experience as well as browsing through WoT forums for either for the console or the PC version. So the math might not be 100% accurate - but I think it gives a good overview.
In case you wonder, why only sometimes in the post battle screen you see "Crew XP" mentioned, you get this in case your crew actually makes another 1% of a certain skill.
So, the Total XP earned in a battle (which is the base for your crew XP) is coming from a couple of sources, mainly the Base XP earned in the battle itself plus some stuff on top:
1) Base XP: The XP earned through the battle itself. More to that further down.
2) Premium Tank XP: If you have a Premium Tank it will net you a percentage on top of the Base XP you earned in a battle. A Tier 8 Premium gives you 10% additional XP. More information here:
http://forum-console.worldoftanks.com/index.php?/topic/38036.... If you have a couple of Premium tanks you can use the method mentioned in this link by Sovietdeath and circle the crew through all of those to leverage the daily multiplier multiple times with the same crew for "free".
3) Ops: there are Ops which give you a percentage boost, for example additional 25% (x1.25 XP). As far as I can see through my result screens, the additional 25% are added on top of your Base XP multiplied by the Premium multiplier (I do not know if the daily XP bonus takes effect as well). If you, for example get 1489 Base XP, you will add another 745 XP (50%) through Premium and on top of the sum, which is 2234 XP you will get another 559 XP (which is 25% of 2234 XP). At the same time, fixed amount Ops (e.g. 500XP) will be added on top at the end. I have not seen a multiplier affecting those at all.
4) Premium multiplier: If you have a premium account, you will get an additional 50% XP. I can confirm, that those 50% is applied on the Base XP as well as the Premium Tank XP. The Premium multiplier also affect Ops with multipliers but not Ops with fixed amounts (see above).
5) Daily multiplier: The first victorious battle each day gives you a double XP boost (+100%) (Special events sometimes spice this up to triple XP). The multiplier is applied, after the Premium Tank XP have been calculated. So if you earned 1000 Base XP you get 100 Premium Tank XP and then an additional 1000 XP from the multiplier -> Overall 2100 XP (not 2200XP) (see
https://account.xbox.com/en-us/screenshot/ea32326c-9b48-4d02... for details). I was not able to confirm if this bonus applies to Ops or not. If anyone knows, please let me know through a comment.
All in all it is pretty much important to get a decent amount of Base XP as everything else depend on it. So how can we increase the amount of Base XP we get during a battle? There are a couple of activities that will contribute to your Base XP (thanks to this page - In German only:
http://wiki.fbfu.de/index.php?title=Erfahrungspunkte_und_Cre...):
During battle:
* First time spotting a tank
* Damaging an enemy tank by yourself
* Team damage to a tank that was spotted by you
* Team damage to a tank that was tracked by you
* Damage to modules or crew by yourself
* Destroying a tank
* Close Combat Bonus
* Capturing enemy base
* Scoring base defense points
After battle:
* Survive
* Platoon bonus
* Victory (+50%)
* Loss (+50%, but only if you get a Battle Hero medal)
There are very likely much more activities contributing to the Base XP than those I mentioned.
Obviously, each tank class specializes on a couple of those battle activities - and you should make sure to play the tank the way it is intended to be played. Light tanks aren't good snipers and Arties aren't supposed to rush the battle field. I'm serious here, I've seen Arties trying to spot and Light tanks staying in the base sniping ... don't do this.
Light and Medium tanks are good for spotting and/or capturing the enemy base + you might get some XP from close combat when circling the slower tanks. Arty obviously for doing damage to tanks, crew and modules, Heavies and TDs for doing most of the damage (supported by the other classes).
Youtube howto for Light Tank spotting:
My recommendations:1) Something to keep in mind, you get more XP when damaging a higher Tier tank than yourself and less XP seal clubbing a lower Tier tank. The higher your Tier in general, the more XP you get (Tier 10 nets more XP than Tier 1). So although it might be a little harder to penetrate a Tier 10 tank with your Tier 8, you will get more XP. Best is if you try that out for yourself - because if your Tier 8 pretty much sucks against Tier 10 (which might be very well the case), you can decide to get a Premium Tier 8 with a higher penetration (and leverage the additional 10% XP) and/or use premium ammo - or decide to go with Tier 9 or 10 eventually to do damage in the first place.
2) Get the Mentor perk for your commander as it provides additional XP to the crew.
3) If you are dedicated enough, you might want to paying real money to get Premium (and/or a Premium Tier 8 tank) to make this less pain full. I'm currently using a T34 premium and got ~400k XP with 280 battles in one week (incl. Ops like the 1500XP for most damage each day).
4) skills/perks: if you want to go for this achievement you likely will not start with a crew from scratch but have a few skills/perks on your crew already and know which ones are beneficial or not. Anyhow, my suggestion is to get the following ones just to make your life easier.
Certainly, every player will have a different order for them or learned completely different ones. This is just the way I did them. The first three are probably OK for all classes, then it splits up:
1) Sixth Sense: you (usually) do not die as fast as you know when you are spotted
2) Brothers in Arms: increasing crew skills helps with everything else
3) Mentor: certainly, can already be the first one but then it's a pain w/o Sixth sense.
for spotting/hunting:
4) Snap shot
5) smooth ride
6) off-road driving
7) Situational Awareness
8) recon
for Heavy/TD:
4) Situational Awareness
5) Deadeye
6) Designated Target
7) Signal boosting
8) recon
9) Relaying
Arty:
I do not suggest to do this cheevo with an arty. However, if you have balls of steel, you already know which skills and perks take you further.
5) I always used only one and the same tank (not cycling crew through the various premium tanks to leverage the 2x XP bonus) or very similar tanks because I figured out that I got confused with different play styles. Sticking with only one tank I figured out to play better over time. But that's just me not being able to adjust I guess. Might be totally different for you ;-)
Happy grinding.
