cause the grind is horendous and all the females wear butt floss and have hip gyrating problems and their is a sole race of little girls in lingerie
to appeal to pedos XD
OT: I'd say GW2, great fun and since there is no sub you can pick up and play whenever and not feel like you are wasting money like a lot of sub based games (that is if you don't play often)
If you are planning to wait a bit, Dragons Prophet, Neverwinter Online, and The Elder Scrolls Online are all set to come out this year. Also if you two like Steampunk I highly advise checking out City of Steam.
Seriously TERA is a great game grind aside. And combat blows GW2 out of the water. But then i can't stand GW2 feels like the try so hard to be different that they shot themselves in the foot.
