Problems:
Resistances are too easy to raise to 100+
One Hander + Shield is an almost useless option
In order: yes, no. Therefore...
Solutions:
* Reduce/remove resistances from plate armor
* Put resistances on shields
* Shields block projectile spells/ranged when facing the caster
* Add 2h and 1h+shield requiring Man-at-Arms skills.
In order: yes, no, no, maybe.
