Thanks for the feedback GrimLefourbe!
You are probably right about the attack speed. The main reason I went for low APRs was flavor but whirlwind kind of ruins that anyway and it is probably really way too strong with the current base damage. Though instead of adjusting the attack speed/base damage I might take a look at the HLAs and remove whirlwind in favor of something more fitting. The original vision for the kit was a fighter that is very tanky and hits hard but has an overall damage out put that is far behind that of other fighter kits, that's probably not true anymore for the current version (if it ever was).
As for the resistences; yeah they are probably also too strong, especially versus a single opponent. Before buffing the kit I got absolutely destroyed whenever there were multiple melee enemies around due to the higher AC. I might consider trading the bigger part of the physical resistences for a bit of an AC buff.
As for being able to equip a shield, I think there is a flag that can prevent shield bonuses from being applied while a magical weapon is active, so at least for the EEs that should be fixable.
I'll try to balance the next version with your feedback in mind though I do not yet know when I'll be motivated to work on the next version.
