Felt like getting this trophy a few weeks back, posted on LFG, quickly got invited to a group of 5 needing a 6th. We did it first try through, no glitches or wipes... We even finished the 2nd half with only 5 people, as one guy got marked by a Fanatic at Oracles and left before he died and screwed it up for everybody. Then we all wanted Raiding Party, so we invited a 6th guy, joined in the same clan, and went and did a 2nd Flawless run since the new guy didn't have it yet. That was a good night.
