I just got this game and I like it alot. So are people still playing it online? I currently have silver so I can't check, but if there are people playing it I would likely pony up for gold for a month or two.

Yeah they do.  It's pretty tough to play now though, since everyone knows all of the tricks.

people may be used to it, but the multiplayer is so singular in it's focus that you can get up to speed pretty quick.  I just started playing it last month and i'm not nearly as terrible as i was when i started

I just started playing it again over the weekend.  I never had trouble finding a game.  I pretty much sucked at first, but I finally got back to my mediocre level of play.  Just the few times that I ran over a few enemies in a group with a tank or disarmed the bomb on the last gold chest at the last second to win the game made my many games of ranking near the bottom worth it.

yeah i still play it online.
