On the first fight, I can do the trios fairly easily. Sometimes I have to get a fresh mount sometimes not. But when the bosses charge, it's almost as if they togather 1 shot me. By the time I can get back up......(They stun?)....they have already killed another of my toons. Also, it seems if I have to switch mounts, they won't pick up focus again at all, no matter how much I mash my button.

6 times so far, best I've gotten one down, which remounted before I could get remounted again myslef. This all on regular.
