Up for a really big bird? Maybe a little BBQ bird? Although more of dragon than anything, Alysrazor does sort of look like a bird. This fight isn't really as challenging as Baleroc, but it does have a fair share of obstacles. You'd better be able to heal on the move, as this encounter will throw a ton of stuff your way when you least expect it. Know where your tanks are at all times, because if the monsters they're tanking become really angry and throw a tantrum, you'll need to step up and keep them alive.
If you have a basic understanding of the encounter, keep reading. You may wish to refer to the encounter journal or other resources to get the whole picture of what is going on and what the different roles are.
