I enjoyed my time in it; well done game, I think. Never reached max level before I got too busy to warrant paying to play that rarely. I enjoyed the story aspects.
Don't take them making it F2P as it being a failure, as some people might be inclined to... Everyone compares every MMO to WoW, and every MMO looks like a failure next to it.
GW2 is running strong; SWTOR is running strong; from what I hear Rift is running strong. I'd say give it a shot!
