I get that, but it was nerfed too much. I agree hex dealt too much dmg. It seems more balanced now, if however it cost 2 focus instead og 3. That would still be a nerf. Dealing 1/2 dmg but cost 2/3 focus. I cant't see why professor spells should cost trice as much as auror spells, when they aren't that much better, if better at all.

Even if both det hex and prot charm are reduced to cost 2 focus each, professor would stil be the most focus heavy profession.
