If the dungeons were repeatable quests and gave exp (god forbid maybe even seals) after every success like Ifrit does then i would be more inclined to keep doing them. Ifrit is a great source of EXP for crafting and gathering classes from the upper 30s on, and is much more fun than sitting there spamming standard synthesis. I found the Darkhold to be fun but I like many other ppl got the majority of gear from it before Ifrit came out. Now i find it hard to justify going back to do it again with absolutely nothing to gain when i could be gaining exp on some other class instead.

It would also be nice if each new thing did not completely negate all of the old stuff. Save for a few pieces (Warlock's Pattens? but even then only for lolnuking), the Darkhold has completely obsolete gear. Yes, new content should have some of the best gear....but not all of it. What i hope happens is that the Moogle fight drops awesome mage weapons and maybe one or 2 melee weapons that are the best, while some of Ifrit's weapons still remain the best for other classes. That way there could still be demand to do both. But hey, this is SE we're talking about. Since when do they do smart things like that?
