Hmm, well, its taken like two dozen games, but I've finally become decent at the game, well, that or I'm facing people way worse than me.
I was mostly playing with Oscar Mike, but have also gotten okay with Rath.
Somehow, though, I think I've done way better with Ambra despite just unlocking her.
EDIT: Now, first game using Phoebe and I did awesome with her. 27 kills and the highest score of the match.
Other than that, anyone else gotten a weird bug where you don't spawn with your weapon. In a game, I picked Montana and he didn't have his minigun, it wasn't invisible either anything - pointing at enemies and hitting fire did nothing, but Hailstorm still iced him and the dash could still damage enemies - just no minigun until I died and respawned.
