Ah, c'mon, Miracle. I'm completely with you in that this news is less happy than "Jack Wall is scoring Mass Effect 3!" But I'm confident in Bioware getting Clint to where he needs to be. It's not like he's going to walk in and just make up his own music. He's going to have to play within the musical boundaries Jack & Sam Hulick established, at least to the point where Bioware is willing to stamp their approval on it.
That being said, how can you judge him so harshly for scoring Doom? He probably got paid $10, spent 4 hrs on it, was heavily restricted with bit rates and mb consumption. On top of that, Doom was, what, ~20 yrs ago. I'm so old now my brain barely works. I would be peeved if people judged my career without giving me any credit for growth in the last 20 yrs.
