It is a tad odd they went with the whole "Progression flag" system I guess it's more of a "Challenge to beat the whole thing before your flag resets" but they should at least let players play in the prior dungeons to allow for endgame communities to grow instead of being secluded.

I'm all for making sure stuff like Binding Coil and Crystal tower stay the hell away from duty finder, but I would also like to see them ease up on the restrictions for a server community to be able to grow. Then again from the sounds of it Crystal Tower sounds like it will be the place to go for endgame shells to participate outside of their 8man groups, and help eachother gear up for the Binding Coil runs, and this also helps prevent certain shell members from being run raged because they are the only guy who wants to be a tank, healer, whatever because he plays with his group and that's all he needs to do, not run 80 instances of Turn 1 of coil to catch all the DD's up.

In a way it promotes diversity in endgame communities and not wedging the small tank/healer community in a high demand situation where they may not be comfortable. Hell I know I enjoyed playing Corsair in FFXI but I sometimes didn't feel like showing up to everyones damn run to restore their 2hours, similar situation with BlackMage.
