Are there mass bugs and problems with the game?
I'm considering getting it soon, but if you say there's major updates, just wondering if it's worth it yet.
Is it stable? Yes, Is there a hard learning curve? Yes, Does the internet hate the game? Yes.
Will it last? Yes,
Honestly though, if you expect it to be WoW, you will be HORRIBLY disappointed. If you expect it to be like FFXI, you'll feel more comfortable but it's really its own beast.
if you're itching to try it, try it. The game isn't going to radically change for the PS3 release.
