Well, that's crap. It is clearly better late game, but early game she seems like she's just ruined for now.
That's something I've always hated about the series. It kind of got better with the later entry of the sentries, but this is a throwback back to EO1/2 levels of weird skill tree progressions.
I made it a priority to max out quick chant, because its TP cost drops all the way to 5. I feel like that's small enough to be occasionally useful in the early game. I won't be using it every turn, but good for when I need some clutch damage.
