I was leery about coming back after 1.0 and I am more or less happy with how things have come along with the exception of FATES. They are game breaking, with extremely high xp reward they are pulling people away from any of the other content and causing people to level extremely fast without earning/learning their role. Pick up parties are, 9 times out of 10, incredibly painful thanks to at least one member having no idea how to play their role.

You could have the same FATE areas spawn but instead of a thousand people spamming, entering the area would drag you into an instance with an actually enjoyable fight. After a certain number of attempts/time the fate area despawns. This would allow people to run FATES because they actually enjoy them, or at least want to, as opposed to those who just want broken XP. It would also allow some NM/Boss fates to drop gear or other rewards without the monopolization that XI had. Some could be soloable and others would need parties of varying size
