Not sure I follow, you can interrupt but he will still finish the cast so you will still be mezzed right? I think that is what I am saying that no matter what you do, the spell will still go off and you will be mezzed. Or are you saying if I hit them in the first 1.5 sec of spell it will be interrupted and the spell will stop?
I'm seriously not trying to argue that they cannot be interrupted, I hope that it can be. It's just I have fought them and read the spell notes and it seems no matter what you do their single target mez still goes off.
