AST Sects: Should it go both ways?

[Miles_Maelstrom]

I mean really, is there any really good reason for Diurnal to be 10% and Nocturnal 15%? Why not both 15% or both 10%? Feel free to discuss how AST would be if both Sects were identical in healing potency increase.

The sects are there to act like one of the other healers. The extra 5% is to simulate the extra healing the fairy provides a scholar.
