While the Red Mage Two-Hour isn't bad on a conceptual level like the worst of the new abilities, it's definitely in the "major issues with potency or execution" pile.

I'm surprised more people haven't complained about it. I'm surprised that I haven't complained about it more, given the massive amount of stuff I complain about.

A two-hour ability that does something so similar to Soul Voice and, in terms of end-effects, also Embrava should be more similar to those abilities in terms of potency and duration. It really is that simple.

The problem and the solution can both fit into the same sentence. It really is that simple.
