The reason why some of us think that a permanent magic dmg debuff for BLM is in other is to essentially bring a dmg boost and a raid utility to BLM while still beign in the range of the selfidh dps (mimicking SAM having acess having slash down), personally this feature should be unique to BLM at least till the next expansion drops since I don't see them changing much to BLM before that.

I still want to warn ppl to refrain saying that raise should be spread to BLM for balance sake because this can and will lead to a senseless spread of said ability if handled incorrectly.
Frankly SE should fix casters by making them worthwhile in their main job then maybe we can start focusing on extras.
