Why the difference in duration?

[Tam_Hawkins]

My guess would be that CNJ/WHM gets a flat 50% reduction while AST is a reduced generation.

I think Raquelle is wondering about the refresh duration, not about the enmity part.

Raquelle, I have only unlocked astrologian and never played that job at all, but could it be that astrologian has a higher MP consumption compared to Whitemage? If so it would explain the longer Refresh time.
