Hmm another mechanic I would also recommend would be Juggle. During this boss mechanic, in a savage turn of course, another player controls your character. In other word, if I were tanking, and the boss cast Juggle, I would be randomly assign to use a team member's healer/dps and someone else would be using my tank ( all 8 people are switch to another player's character class for a temporary time). This mechanic sounds like it would need a LOT of development though, I don't know how easy can SE make this happen. It would also give static a challenge, because what static doesn't love challenges.
