Im starting to get the impression that possibly in destroying the worldstone, Tyrael was corrupted by the souls of Diablo, Mephisto and Baal all at once. Maybe because just one of them alone wouldnt have as much affect on Tyrael. He fights them off for 20 years and gets banished from heaven once they realize what's happened to him. Then you see his mask off and either wings or horns on his head and massive red fire instead of light and slowly the three prime evils all take control and reveal their new form, the hydra
I think it's more plausible than tyrael being only consumed by diablo and would elso explain the hydra and unrecconable force. It'd be cool if you get to fight tyrael in his angel form right before he transforms but then he gets away.
And then bring in belial and azmodan and lilith and all the demons they can think of to take meph and baals place as boss fights.
Fuck you, I'm a dragon.

Id especially like that I'd name my character LordofPussy666
