I blame the lazy members of my guild who couldn't manage to make enough raids to get geared up and now force us to run the same places over and over for their stupid gear. The monotony of raid instance farming is what burns me out, and it affects the performance level of players as well. People get lazy, it's hard to focus, etc., when you're just farming the same place you've seen 50 times. Guilds could just stop but then they risk losing people or people being even MORE lazy when the devs finally decide to release new content.

At least from my raider perspective, the raid system is the cause of burnout. If I didn't *have* to raid a couple nights a week (well it's a choice but if I don't, I don't get dkp, I look like a bad guildie, etc.), I wouldn't and the break would do me good. That actually makes it sound more of an anal moral flaw in my own character that I feel so dedicated to people in a game I push myself over the edge. Dedication and responsibility are great, but everything in balance.

That said, I actually am on a couple-week break, but breaks are dangerous (from the guild's/game's pov) because they tempt you to live your life in reality. I know, the heresy.
