Jedi Master Kenobi ultimate - Share your guess

i want to imagine he will grant a 1-2 turn "cant be targeted buff" to his teammates while healing them. which will essentially make him a taunt, but their will be no by-passing it. and while he has this sudo taunt he can counter attack anyone for larger damage then normal.

(TBH im thinking of the highground stuff from EP3 with the couter attack part.)
