I've been playing MMOs as a raider, or the game's equivalent, since UO. Even now, I play about 4-5 hours most nights, more on the weekends. I love the game and am "happy and re-subscribing." I also don't feel that casual players opinions aren't a good barometer about a game's quality. What an arrogant, elitist comment!
I think the issue here is people who don't seem to understand that a game at launch isn't going to be as polished as certain juggernaut games with years of experience, no matter how good that games programmers and designers are.
