The game is a good game in many respects but it has a couple of severe design & performance flaws.

The game is slowly bleeding numbers, which the trial helped mitigate, but I personally think the major reason they have currently only a slow decline is the fact there isn't much new competition around right now, once the other AAA MMO's that are in development start to hit the market I fear that the game will suffer pretty badly, all depends what the devs can achieve in turning the game around between now & then, & just how good the competition shapes up to be.
