My match where I reached gold was a bit close for comfort:
https://gfycat.com/smartnextchihuahuaSince the update, legendaries are much weaker so I barely run any. 3 shepherds can beat most of them, so it's a waste of power.
Here's my gold team:
Me: level 12
Ink Grenade: level 10
Sentinel: level 8
Snub Soldiers: level 12
Old Man Marcus: level 2
Hammer of Dawn: level 2
Shepherds: level 11
Reyna: level 5
Nemacysts: level 9
Emergence Hole: level 4
You've only got two pins that can capture, but OMM can capture so fast and the snub soldiers can split, so it works out. With the other pins, think about what counters what and play accordingly. See the enemy using a Carmine, Dom, Marcus etc? Time for Reyna or Shepherds. See an overwhelm strat coming (Shepherds, Snub Soldiers, Wretches, Lancers etc), nemacysts are your best friend. The Sentinel can also be good against spam, as its shield will distract and give time for other pins to come help/the turret to take them out. The rockets are good against grouped together units. See snipers? Ink grenade time.
The Hammer of Dawn is necessary, as if the other player is running it you're at a disadvantage in my opinion. It's an easy, guaranteed 200-300 damage(not sure on the actual amount) which often decides matches. If you can ever whittle the opponents tower down to say 400 before they have yours down to 400, you win. Ink grenade + Hammer, game over. I had a lot of draws, but when games were won or lost, it was mostly down to having guaranteed tower damage towards the end of the timer. If you see a high level Grinder or something which is too hard to take out with your units, use Hammer of Dawn on it. If it clips another group, you will come out ahead on power.
With the ultimate, you could definitely make a case for both. My Emergence Hole is higher than Seeder, so I stuck with that. If you see that the other person has Emergence Hole, use yours straight away on their tower so that they need to respond. If they place their ult there, that's to your advantage. If they place it on your tower, well, you come out even. It is best used to distract the tower while you get something else in there to hit it. Reyna, OMM, etc. For the enemy hole, always use Shepherds near it or Snubs. If your opponent has a Seeder, decide (based on their overall level) whether you want to go for the win or make sure that their Seeder is ineffective. Sometimes the win is the option and you go straight for the tower as soon as Emergence Hole is ready. Other times, you may want to hold onto it to counter their Seeder. Play it on the Seeder as soon as it appears and it will likely die with a bit of support.
It's frustrating with the p2w aspects, like, some games you know you don't really stand a chance of winning. In those cases, play for the draw and try for next.
There is definitely strategy in this game, but the p2w overrides it in many cases. In Bronze League, I can spam pins directly in front of my leader the whole match, nowhere else and still win or draw about 50% of the time. What a joke, lol.
