Blizzard just opened up on the beta class forums, a new sticky they will be closely watching.
Here is a quote from a Blue on the subject I am bringing up with you.
"We feel the numbers are in a pretty good place right now. If you’re a theorycrafter who has been waiting for things to stabilize before submitting your class balance analysis, this is your cue to have at it."
If you are on the beta and have balancing concerns as far as PvP now is the time to blow them up about it. To me it looks like the are getting ready to begin the final pass on the numbers and the balance before 5.0 opens on the PTR.
So this potentially is the last chance that PvP players have to demand a balanced season before this thing goes gets that sleek blizzard veneer.
So go Post let your concerns be heard!
