Tough.
Went in there on my Wizard. Ran out of time while working on the puzzle, after getting the Reaver down with only 90-100 seconds on the chronometer left till the bomb went off.
Had four possible puzzle outcomes left, was pulling one of them when ka-bada-BOOM.
Finally, there's a use for taking a second person into that raid. It's still easy in a group, but solo it is a bit more challenging.
Oh and the much-discussed Disintegrate? In ~18 minutes fighting the Reaver, he fired off only three. All three physics missed me.
I never thought I'd say this, but I had fun in the Reaver's Fate...
