I have always been playing DPS and healer specs, and I'd like to try tanking. I understand I have to know every fight that I tank beforehand, from the tank point of view, and preferably from the point of view of other specs as well, lest I wipe people unnecessarily. That's fine, I can do that.
What's worrying me is something else: most fights use two tanks and so there should be some communication between me and the 2nd tank. My question is: how much of that communication is required and how it is generally performed? How, say, the swaps are normally done - do we just look for debuffs on each other or do we whisper 'take the boss' or what?
Could fellow tanks specify what exactly they say to their counterpart in various SoO encounters, just as an illustration?
Thanks in advance.
