I just tried to get a heroic done as part of a quest where i have to do 5. The first god damned strike is the darkblade. One afk'er so the other guy and i go forward. make it to the big room/area where there are 2 chests on either side and witches and shit. Not fun. The other guy dies once and bails. So i hang back for 10 minutes. NOTHING! No one was matchmade into my strike. I mean, wow. I never had that problem before TTK. It's very very real though
