Trap bait indeed.
During the first week of 4.2, I ended up in a Byakko EX party led by a DRK tank with a PF description that was basically 'I want elitists with 90+% percentile scores'. I actually had a historical percentile of 100 for the fight already, only because I had the highest recorded DPS for days 1-2. Never said a word though, even when he started worshiping me even though I knew it wasn't that big a deal (getting high historicals during the first week is really more a matter of luck -especially for Bard-, and I guess ability to learn/adapt mid-run/guess mechanics very very quickly). I did manage to convince him to stop checking the damn parses and let a bunch of people who claimed that they were stuck at enrage and just wanted to clear stay in the party, if only because he was going to be waiting forever with the criteria he set. That, and I checked -his- records and knew something was up with him.
Indeed, when we got in, he didn't even know how to properly tank swap, so I watched in horror as it was either me or the poor RDM that got repeatedly slam dunk'd into the ground even WITH our enmity reduction skills. After several pulls, we all decided enough was enough and we weren't going to carry him to a clear, especially when he started blaming the rest of us for not DPSing fast enough and not using our enmity reduction properly. I left and tried to reform the party while looking for a different tank, and about 4 members of the old party returned. We cleared first pull, which meant that the failure to tank swap during the slams was the only reason we failed to clear before. Oh, and it turned out that half of the new party earned their first clear that run too.
We went on to farm 8 or so runs, a few people left, got a few more people that came in their clears, and so on without any issues... There were apparently other people parsing me because I got tells from a few of the party members wondering how the hell I was doing so much damage as a Bard. Bard is really easy in Byakko EX though.
