I remember in WoW dueling outside of Ironforge for hours, and I ended up learning all the other classes by the trial and error of my duels. And even the class that was my weakness as a warrior, which was paladin, I stood a very solid chance in a fight.
My Ask of the development team is to please maintain this kind balancing in the PVP across classes. I know balancing down to 1v1 is something you are refraining from doing but I hope that doesnt mean that you ignore that 1v1 dimension entirely.
I believe any self respecting player is going to want to know that their character should be able to "hold their own" if played well.
