My missus can only use one hand when shes playing as a result she sometimes messes up with standing in shit or has a hard time switching targets on the fly hurtin her dps. When we were alliance she couldnt go into heroics on her own because 1 mistake and she would be ripped a new one and get vote kicked before she could respond.
I switched to horde when half my guild switched and conned her into switching too. On horde side she doesnt have these problems, well ok she will get the odd douchebag but she has yet to be kicked from a group. Nothing changed shes still playing a hunter although her gear is much better now that she can actually complete heroics and lfr.
Granted horde have a higher pop for one reason or another but for some reason the ratio of douchebag to normal well adjusted human is vastly different to alliance.
