Blackmage is absolutely fine as it is now.

Like, back in heavensward ui and af had a timer and enochian had a separate timer as well. Back then you had to juggle both and if one of those went out, you basicly stopped dpsing.

This job has a history and if you have been there from the beginning then everything will feel organic and make sense

Beginners now have it a bit harder, since they dont see what actually changes and what purpose those things once had.
