Gindan has a AOE that will one shot with a red emote "The commander shakes with rage as he prepares a savage attack." Joust this, and be prepared to rez everyone who doesn't joust or whom the mob goes after. Two tanks help with this. Kill the adds when the spawn. One of them will end up with a bomb, and when you kill him it will explode and do damage to the raid. It's best to pull the adds away and off tank them.
