Painaid, you strafe with 'e' and 'f'? interesting.
At one point i rebound my 'a' and 'd' keys (lolkeyboard turn) to more important things (trinket/bandage) but it didn't work out; I eat food/do other things in pugs and such and keyboard turning is always easier when it actually doesn't matter (and you have one hand open)
EDIT: The only way they could nerf backstrafing would be to nerf mouse-turning, which would be stupid. I guess they COULD just make it impossible to turn while jumping...But why would they? It's always been a critical part of PvP. There's no problem, so why would they destroy strategy+depth if there ain't nothin' to fix?
