We are not all Soloers or DD and i feel Dnc subjob is getting to mutch already....

Healing Waltz and high tier cures give to much recast in Party situations to be a reliable supporthealer.
That is an Issue.
But letme ask you.... as you Mentioned Phurba often. Given in my opinion totally situational. (NOT BAD)

Would you like a Stace Ability that "Cuts recast times off by 40% but restricts Weaponsiklls and lowers Evasion" ?
Well guess what. I would. And i would use Phurba then.... offhand.... sometime......
but i would personally prefere they added a Magian Waltz Potency Weapon. Mages get a Staff with Cure Potency.....
