Tips:
Use different weapon types. Eventually you will 'max out' a particular type, like assault rifles, and won't earn any more exp for that type except for ribbons and medals earned as you get kills with it.
You can earn exp for "spotting" vehicles with the recon class. Just spot a vehicle in a large game type like Obliteration, then unzoom and look for another vehicle to spot. You can re-spot any vehicle as soon as your previous spot on it wears off for more exp.
Squad Death Match and Team Death Match tend to be the most exp per hour because these matches end in around 10 minutes or less (usually) and if you're a solid player you can earn 2,000-3,000 exp minimum per match barring ribbons and medals. I got 13,000exp one match b/c I got a couple medals and a bunch of ribbons. Not bad for a 9 minute match. Beats the hell out of spending an hour or more in a match of Obliteration or Conquest only to get 4k or 5k.
On the latest double exp weekend I had a couple of matches gain me over 30,000exp with all the bonuses. I gained 400,000 exp in one night on tonight's double exp weekend so it's highly advisable to wait for them if you dislike the campfest MP as much as I do.
Rank List******
I haven't been writing down my exp as I went along so I have to start from where I'm at. Gonna shoot for at least ranks 1-25 for the lvl 25 achievement but will try to list everything to rank 100 as well. Thank you to the following contributors: Krayzie, Acepurvis.
