I am aware of the low AP cost of warrior skills etc as soon as you have some points in STR. I should revise them. I think indeed more of them should cost just a bit more than the AP you have so that you'd have to save AP up for them. Especially if they are "high damage dealing skills".
Resistances for enemies are indeed too low. There can be enemies with low resistances, the real grunts, the ones that you can deal with easily, but they should at least be different so that you have ideal targets and more of a "chance to" instead of "100% chance". I changed some of them, but I think that change just didn't make it to the beta.
