Wildstar tried that but the MMO genre has just moved past that sort of system now. Those niche games aren't going to survive in the current MMO environment. So your choices are either play one of the current niche games still out there or adapt to the new style of MMOs.

And it isn't even like this is new. The genre started going this way with the people who left EverQuest and others of that time period for (at the time) less grueling options like EverQuest II and WoW.
