Not everything that is new is good also.I personaly hate the idea of player generated content and will probably be the one thing that will prevent me from playing this game unless it will be almost perfect in every other aspect. I am a gamer , i play games to have fun, i dont want to do the dev's job for free.Of course…
I respect your view and somewhat share it, I too would like to see something more than your average WoW-ish idea of endgame, personally I would like lore and character development to define this game more than anything else.
Raids is what most MMO players are looking for because they played WoW, I am pretty sure this game won't be very PVP orientated and 5-man content gets old really fast. No raids, no long term player base.
