As with 2.4 and more than likely 2.5 SE have started adding an expert dungeon as part of the main scenario.
Does this irk anyone else for the main reason that you need to complete the main scenario (or at least upto and including the dungeon) to unlock expert roulette? It doesn't allow you to make the content last or do later just to mix up things.
As what I would do is, week 1 of the patch unlock experts new WoD and some of the lesser quests, eg post moogle quests.
Week 2, start main scenarion, week 3 finish main scen, week 4, do hildibrand (while capping tomestones, raiding etc. then week 5ish pops for the next patch 2,51.
But I can't unless I want to miss out on doing experts :S
