I think it looks really good, i tried it some time as well and personaly i didnt have problems with the resists. Maybe you could ad a mechanic if a spell gets resisted the next one has 0%chance to resist. This way you can still resist important spells but at least you are sure the next one wont be able to get resisted.
The crit damage on archers is kinda over the top, i guess you noticed that already and since its a work in progress i expect that to change.
With that you could make concentration a more usefulls spell, on the live server 6 hc is more usefull on a weapon then 5 concentration. Didnt change i would really like to see something done there.
Besides that great work, i like the changes
