Where is the BLM nerf?

[Jinrya-Geki]

ARC is a class, BLM is a job. They are not comparable.

Were you PL'ed so you didn't learn these things?

Any class can be a support class. The armory system allows them to be.

Blm is a job, you can't give it cure or stoneskin or protect.

Therefore arc can be and is a support class dur to the armory and job system from bard.

Thm is designed to be support/dd as well but your title is about blms.
