Regen II I agree with, This...I swing toward Munkey's statement.
Locano, something that whm and blm will always have over the rdm is ~ga spells...I don't mean to be reduntant (since we all play rdm), but rdm only gets poisonga and diaga. I totally agree with you too, dispel and refresh are the RDM highlights in party play, ideally you'll have a whm in your party so you don't really need this. Besides RDM is busy as it is...do you honestly want people saying "Regen III please"? *cough cough* haste *cough* refresh :p
