I'm sure there's at least a few others that play this since it's one of the largest mmo's out there and it's free.

After a recent huge update called the Big Bang, it almost entirely changed. (most notably the experience curve, it doesn't take nearly the amount of grinding it used to) There are also new classes out with another one coming next month.

It's a game I think everyone should try, it's not something you have to completely dedicate yourself to like WOW.

I gave it a try about two years ago. The grinding got so bad that I've completely given it up.
