OP this is an MMO so a lot of the things you're asking about aren't able to implement.
-Open World content works great for single player games but when they are used in MMO's open world doesn't work because it turns into a massive zerg feast and hard to access because of lag.
-Random bosses again works well for single player but in a MMO are a nightmare to balance even in the more action MMO which still use heavily scripted battles.
-Crafting high level gear equal to myth or above not gonna happen because it will make doing dungeons and raids pointless

Renik a lot of the content you want is geared toward single player games but not MMOS. If you played a lot of MMO's you know they can't just add content without balancing it with everything out.
