Please suggest more terrible WoW ideas.

It sounds good at first but there are two major flaws with it. The first is that it segregates players, thus robbing players of the ability to play the game with people who have different styles and forcing the large number of people with views in the middle to take a stance on something they'd prefer not to. The other is that it creates more work for the development team to balance every patch - if they add equipment it would have to be balanced for "required level" and "optimal level" servers, when they adjust PvP and new areas they have to consider both PvP and "normal" servers, etc. There are also additional issues with things like costs for maintaining servers for the less popular "options."
