Ever since I started multiboxing I've been in a raiding guild. Fortunately I've got really, really cool guildmates. When Wrath hit I PL'd my druid since he'd be my main and started gear him. We needed healers because healers were in short supply on Madoran in a bad way. From a week after Wrath Launch until last Friday, I'd been to every heroic but 1, every raid but 1. I had every single raid lockout. I *always* had raid id's for 10s and 25s. I simply got way too burnt out on healing. I did it for the guild, but it wasn't that much fun when you've just spent 4 hours in 25 Naxx and you've got people asking you to do Naxx 10. It is very hard to say no in these situations and it really makes me feel guilty telling guildies no, but sometimes you've gotta do for you. If it isn't fun, don't do it.
