Chad Mages What else would you want right now for our class

Making fire 1 instant is a buff.

True enough, but largely insofar as it makes timing a tiny bit easier. Potencies wouldn't change, and with the same MP costs, same number of casts.

You'd lose less damage in movement phases compared to using Scathe, but counterpoint, you would have avoided Scathe anyway.
