These kind of threads are pointless and really not needed. No matter what you give class A, class B will always have a counter. Its too early to tell the specifics of each class and more than likely there will be many nerfs and buffs to each class before the final version of cata is released.
So making another thread about the pointless threads was...useful? There honestly isn't a lot to talk about right now, I'm fine with people wasting posts here for a while.
