I am also a CO lifetime subscriber, which came with a big dollop of egg on my face. I really do not like that game.
I don't think it was mentioned here, but the thing I really dislike is the world design. Part of that is art style, but mostly the existance of a very immersion-breaking hub area that I suppose is there for player convenience. It's an inescapable eyesore in the city world.
Aside from that, having about seven million different currencies with no idea which are important, and a very dull levelling experience, I don't see myself going back.
