If you could ask 1 question to the Devs

[Deceptus]

They have a "tank" mode but I haven't figured out how to make them pull (make the first attack). I'm guessing it doesn't exist, but if it does let me know. Probably has something to do with the hatred for "pet classes".

Hit with an auto attack, the bird will pick it up then.

And then in about 10s if you're a competent DPS you'll be pulling aggro off the bird anyway because their aggro generation sucks.
