When I did the fight as a white mage I did not have Regen (I was level 34 at the time) and I basically used Cure and Cure II since Medica is too expensive. Overall, the fight is not hard to heal once you get used to the damage pattern and the timing of the boss abilities. I would also assume that Scholars have a much easier job since the fairy does most of the work, even when they are turned into stone.

The big issue that I have are the servers since I am European and I have to live with a permanent 1 second delay. Even if I currently stand outside a red circle, it might still get damaged depending on how fast I moved. Certain abilities simply cannot be dodged by European players (like the wrath of earth in the last phase of the fight).

Funny how playing this game made combat in WoW a lot less boring. The faster GCDs and the lack of delay made me feel so good that FF XIV will probably not last very long for me (especially when SoO comes out).
