They never fixed any of the bloody bugs! I don't care about the graphics, because one you play the game it's amazing and you get hooked.
Still, the balance issues and bugs are just horrible! Some classes have to farm in order to level, because they suck that bad at pve. pve is really buggy, the game itself is just so buggy that it's virtually unplayable at times (I got stuck in a building and had to wait a couple hours because /stuck wouldn't work for a gm to move me).
The game is so old yet so buggy! If they had fixed all the issues with bugs, and just balanced the classes and gameplay they have... the game would be a hit, no doubt.
