The problem I see though is that levelling is so fast in general, even moreso with FATEs, that once someone completes a dungeon once for their story, there's no need to go back to it ever again. Sure the dungeon gives exceptional gear for its level, but the problem is that those levels can be completely bypassed in a few hours by running FATEs with subpar gear, or even no gear.
Honestly, gear can be completely bypassed until level 50. There's no community pressure before level 50 as far as gear since everything can be solo'ed easily with subpar gear. The only real solution is to nerf FATE xp into the ground and force grouping and drastically increase levelling time, but the MMO community as a whole outside of FFXI have deemed that unacceptable over the past 8 or 9 years. So we're kinda stuck in a situation where levels 1-49 are stupid easy and fast and content is disposable and meaningless.
The real game is at max level I guess.
