What if blizzard completely wiped every skill and ability from all class, and completely redesigned every class from a clean slate for the next expansion?
To me class are the core of the game because nearly every major and minor thing a player does he does is with his/her class. To me the classes have stayed the same for way too long. Sure we get new skills and mechanics from time to time, but when was the last time that you heard from blizzard in a patch note "we completely redesigned X class". Exactly, because have never heard that. It's time for a paradigm shift.
Wow is plummeting in subs. If there was ever a time for big changes, then it's right now.
