Here is a trick to make the demon boss in Bot easy as pie. Start off your team as close as you can without aggroing him. I center my group in front of him really close. I lay my totems out and send the pally in. I tank him in the middle of the sac alter and where I left my guys. After every sac you have to taunt him back to the middle. Once he sacs a guy just heal that person the few seconds he takes damage. What this does is lines your team up so you have those not saced facing the alter and those saced facing your other guys. Just make sure you taunt after every sac and keep him in the middle and it should be very easy.

The flower boss is a pain in the ass for me. I still have not figured out an easy way to do him yet. If anyone has one for a Tank, Healer 3dps team post it please.
