Only real knock I have against the game is the non-scaling dungeons. There's three of us in the group and the dungeons are just too difficult for that small of a party - need a full group. So didn't get to play much of any of them due to that.
I really like the game and have recently been playing it. My major complaint is that with so much of the content soloable, players seem to be disinterested in grouping. I always place my character in the looking for group list, but I don't think I've ever seen more than 2 others players do the same. It's wonderful to have a game that's really rich in story and have the majority of it playable on your own, but group experience seems to be the victim of that. Getting in a raid -can't recall the exact term- is an even bigger challenge. I've done monitoring the main chat channel for group raids in the main hub area, but there seems to be little activity in that regard.
