Sorrry I'm late to the party, and this might have been covered already (didn't have time to read everyones post)
If you think Cura II sucks, you should stop playing WHM immediately, because clearly you know nothing of your job. It can cure upwards of 250~350 HP if used properly with capped Cure potency gear. If you're getting 100~, you're not using it properly.
Try using it with Afflatus Misery on a mob like Dragua.
Secondly, how is it an "Underpowered Curaga"; it casts a lot faster - and uses only 1/3 of the MP. (Cura II can easily compete with Curaga III)
You call yourself a seasoned WHM.... lol
Let's hope we get Cura III - really get the party started.
Just because you don't know how to (don't care to?) use Cura, don't poop on those of us that use it with a lot of our encounters.
