First of all, while allowing us to switch classes for the last Job quests is nice to one extent, it would certainly be more 'interesting' and thus 'challenging' if this wasn't possible.

Cutter's Cry is an extremely challenging instanced raid meant for full parties of eight adventurers, consisting of Disciples of War and Magic at level 45 or higher.
Extremely challenging content that's been beaten less than 48 hours after patch? {Hmmm.}
