If something needs to change in the MP is the frigging quitting mechanic. Install some sort of penalty, like losing credits or something similar, but they need to do it pronto.
I've had it enough with people leaving mid matches in Silver and Gold. As an Infiltrator I can survive for a while, but it gets damn near impossible with other classes and I'm usually left losing some bonuses I used for that round. Frigging idiotic.
