Um, no. Classes [SPECS] were never even close to even in any version of this game. This could've many different reasons - I just believe that Blizzard doesnt want to balance all specs for whatever reason, because there's no other explaination after 12 years.

Again, wrong. They have their own in house sim tools - this is all we know, except that their in-hose sim tool is a COMPLETE FAILURE. They maybe want logs to back up your claims when you write to them, but they never balanced specs around actual live logs.
