Mine would have to be the Assault class, boosting into a room of 5 or 6 enemies and blowing them sky high with a grenade launcher never gets old

I think I like the Assault. I have been playing COD4 and RE5.

Tactician. i like to be "tactical"

Sabotage. Noting like having an enemy dude run right past you, then you turn around, follow right behind him and pop him with a melee to the back of the head then hearing him say "WTF?! I HATE THAT DISGUISE SHEET!"

I like being an engineer and goddam am I the only one that thinks that the assault class is killing the multiplayer for this game?
To see a guy enter a room warp around and spam rockets or grenades killing everyone in the process is infuriating...

Assault, because boosting on the capture the flag segments ensure instant win.

Medic and Tactician for me, I like the classes that can change the tide of battle. More people really need to revive, and more Tacticians need to stop throwing spawn grenades at pointless spots.

I like being a medic because I can keep healing myself (and others).  Scout is fun, so is saboteur, and tactician, and engineer... Damnit, I like all the classes.

I played a lot of assault at first. But recently I've been playing as Tactician, but using C4 as my secondary. I like taticians because it infuriates me when my team loses because our tactician isn't being smart with spawn grenades, so I've been taking into my own hands more often. C4 works really well when you learn a half dozen good spots to lay it in each level.

Medic when im not tired.
Sniper when tired.Im lazy.Sue me.
