i thinks mmo's should take the idea blizzard has with diablo3, they will have a hardcore mode on each server where u can chose to do, those players have a seperate auction house then those who don't do hardcore mode. so in reality it is 2 different gameplay styles all on same server.

maybe mmo's can layer servers and still have full servers of players and still have different game styles in them rather then trying to create a mmo where half the content is for this group or that group cause i don't think this type will ever truly work out. this would keep all types playing together in whatever parts are similar and still keep the non similar things we enjoy in it. can have easy mode and hardcore mode coexisting without hurting each others gameplay.
