I think the WoW juice is starting to run low after the longest continuous stream of time I've spent playing since the game was released. I'm in a guild with friends (which I'm not going to leave), which hinders me in doing serious raids. PUG raids are painful and make me want to die, which prevents me from doing anything other than, at most, 1d Sarth (never ever ever Naxx--the one time I tried, we wiped at least once on every boss and 3 or 4 times on Heigan). I'm pretty much at the pinnacle of heroic gear, and I don't really have any desire to do the more onerous achievements (like Loremaster, though I am pretty close to 50 mounts now--I have all the rep, just need a little more gold). I have three 80s, so I'm not in any hurry to level up alts, though I do have cloth, leather, and mail heirloom shoulders now. Most of the time, I just get on to chat with guildies.
