We did this fight on the first pull without an enchanter, we did have a dirge and a troub in the raid but power grew scarse near the end of the fight. With a good enchanter this fight should be pretty easy.
We do this fight with two tanks standing side-by-side; pull him down the ramp so his back feet are near the bottom of the ramp; raid force should be where they could "reach out an touch" his hind-quarters directly behind him; the MT holds the mob until he mem-wipes and the OT then has agro because the OT has hate in the 90s just under the MT on the meter therefore the mobs doesn't move much since all raid force is right behind him. MT then climbs back up agro meter until he claims all agro and repeat. Our scout would tank an add in the event a raid member went down and popped an add; adds go down easy.
aprox every 1 min does wild bucking aoe+power drain
Secret to this fight is not let anyone die. each time someone dies, an add spawns that hits hard. So if one dies, the add spawns, kills someone, another add....chain reaction, wipe. Easy if you stay focused and take care with aggro and memwipe
