That may be. Mostly the people still stuck at T9 are there for pure performance issues; either the mentioned lackluster dps, mechanic handling or finding a proper group to do it with. I'm not counting people new to the game or raiding, but rather those people who are stuck at the instance for months.

Overall I have pretty mixed feelings about the echo in general. While it's now easier to go farm and I can generally play them more easily with a group of not so hardcore frands now, it also rewards complacent people who do not pull adequate dps as you mentioned. I think there should not be lazy people in an instance regarded as the current hc end-game in the first place. I've already seen MNKs with 200ish dps in the FCoB. O__o

That is just my opinion though, gratz to anyone just getting into the FCoB now. Hope it's as much for you as it was for me.
