Good show! Random thoughts:
One of you should have walked in alone to spring the traps. No sense in both getting hit.
Ragers should have waited until you hit the giant, then struck as a group. Unless that violates rager RP. Does it?
Thief was not going to drop your weapons with kidney and gut shot. Should have gone for knockout, or maybe dirt kick Drissa while she's aiming at the giant and then spam circle stab.
Would confusion darts on the healer have been useful? Would it have messed with his ability to target Drissa with heals?
