Horrible no way, not compared to some games. I'd say on par with the standard.
played the others as well AoC was cleaner but lacked content. WAR, i'll let someone else comment on it but yea, some similar issues.
I plan to play the others as well and before this gets closed, I think you should also include Blade and Soul with Secret World and Tera, although i'm unsure of release dates, and thank you for letting me know on the other 2.
