Hate to necro a long dead post but I'm finally getting around to starting this fight. I have absolutely no problem five boxing my way to the last phase but I can't seem to make the macro work. I've gone so far as to go up and get the daily with the same dragon to work on it, but the problem seems to be in the /cast on a vehicle.

Did they change that at some point, do I have to refer to the vehicle specifically? If I go up and get on the dragon, something as simple as /cast revivify doesn't do anything at all, yet alone the cast sequence. I pulled the follow out as well since I can just kick in Jamba autofollow when we fall. It's pretty frustrating since I went in and one shot all four VOA bosses right before (first time I ever killed the fire guy yet alone by myself) and the first two phases are so darn easy.
