Well Tass, they are adding a lot of new stuff with the Battlegrounds patch coming out soon. Plus just the participation in the world is enough for me to fly. I have seen few if any bugs, and the game engine and world itself (and it's apparent lack of almost ever having to load...ever) is very enticing to me. Plus in general I find it to be less boring than other MMos, if only because you have all of these crazy quests to keep ferrying into new areas.
I also have tons of great stories and pictures from it too. It is just a good, barebones setup--not a lot of bull**** like some other MMOs. Either way I think it's great and going to get better, personally.
You guys are all way more hardcore than me. I have a few awesome swords but my character isn't even in the 20's yet. Heh. Still loving the game, especially when I come across RP'ed scenarios.
But then again I love Warcraft more than any other series, so I may be biased. :0)
