Niccus, by sniped with a LMG, is the weapon medic has? like the 249 on css? That weapon does work like that, single shot is like a sniper... two shot and it goes spray and pray
About the bases one way.. well, you don't really only one way... most of them can be exited in other places too.
And yes... EA is pumping games like there is no tommorow, so things tend to come out a bit broken then they should, as a software developer (part of me is) I expect my own stuff to come out broken in some places too.. but then there is a period to recode some lines and fix the damne thing...
Maybe some companies take beta testing a bit way too far.. like Blizzard...
