I played the heck out of that at the beginning of the last school year. What's not to love about fighting other people as transforming robots?

It's all pretty balanced too I think. So long as people remember their class role... I loved playing as the medic for the speed and flying and would actually heal people. But of course when I went to the other classes to get Prime status (yay 50 achievements :3), rarely did the medics care to heal you.

Aye, it's mad fun.

Leveling my scientist and infiltrator seem to be the easiest though.

Oh it was immensely easy to level them, yeah.

I think the only one that took a while to level was the Titan. Yeah you're big and tough, but being slower when everyone else is probably an Infiltrator (is that class still popular? My [poor] memory's telling me it was very commonly used) and zipping around you made it harder to get kills. I think I did the most objective gametypes with the class than the others, because defending a spot was so easy.

I'm only doing Team Deathmatch so far (and on the PC) and teams on medium-sized maps tend to be pretty balanced, actually. I know I switch between classes a lot.
