Every major MMO has some kind of cap on endgame content. It is really unrealistic for you to demand that they remove the cap. It's there for a reason. If there was no cap then you'd finish everything in a week, get bored, and quit.

If you don't like it, Everquest Next and Archeage are right around the corner. I'm not going to recommend Wildstar since it's likely to either have caps or be p2w.
