do you know what they actually did ? they changed combat system and made it so everyone could be jedis lol blizzard isn't changing the combat system. they are changing they way specs work so you wont' be limited to certain builds for saying doing dungeons or pvping. for instance alot of ppl want to do arms pve, and fury pvp and actually be able to do good job well blizzard is addressing that type of issue with this change. It has nothing to do with combat system really.
Do you even know what wow is about? WOW is about being super easy and fun for even the 10 hr worker who only has 1 hr to play the game a day. That what WOW has been and always will be and is there goal. To make wow fun and easy for everyone.
