I tried it on my 60 rogue and this is what I came up with (Might not be correct but it's my guess):
AB: You get experience according to your teams points and then exp at the end. For a victory in AB I got ~16k Exp.
WSG: You get exp for your team capping the flag and at the end of game. My team was terribad but you get 4k at the end. I assume capping is also 4k/each.
AV: You get Experience for killing the first boss, destroying towers, and killing the final boss. You also get awarded honor (maybe determined by what the opposing team was able to take). For a winning AV I got 43k experience. That could be a viable way to level with 43k exp in 10-20 minutes.
Has anyone else tried this out?
