1.) Bad-mouthing doesn't make your arguments any better.
2.) In the text you quoted I justified nothing. I talked about the fundamental approach to pvp design.
3.) Removing or nerfing (or buffing) some abilities changes the power of certain classes but does not solve the overall problem. It just shifts which specs/classes are too good, which are average and which are bad.
4.) In order to achieve balance you need an approach that can deal with so many specs in pvp and keep them balanced but diverse. Simply buffing or nerfing some abilities doesn't achieve that.
