No one expects DPS to carry like Dafran; some of us get irritated when the enemy team has a Pharmercy and DPS won’t switch off Reaper/JR or some nonsense like that. IF you cannot aim well, don’t be DPS, I hate to say that. Its too incumbent upon DPS players to learn at least some aim skills to take on killing things at distance.
DPS not playing around shields, not peeling for tanks and supports (ever) then trying to do dumb crap like playing too close to enemy spawn… these things are all constant realities.
