Think you only can toggle sprint on/off So you dont need to hold shift to sprint. You will still need to press w to move^^
No there isn't, but we need it.What I did was map the sprint to my Q key.Then when you subsequently press your W key it toggles sprint which is a sort of auto run but not as good.
I'd be in favor of an auto run key. Especially when I'm playing sniper...so much easier to hit a target moving in a straight line <G>. Didn't know about = for the tank, that's great info!
