been playing for awhile and first time posting.
currently it seems that using two handed weapons is just worthless especially compared to the other fighting styles/ specialization because of the ridiculously high AP cost a simple way I see to make it more worthwhile to be a change in two handed style/specialist bonuses as follows:
1: changing the fighting style bonuses from the current (0.7.1) bonuses of +30% damage to a reduction of 1 AP per attack per level with a +2-4 damage, to me it just makes MUCH more sense that as you become more proficient with the weapon it become easier to use and you can do more damage.
2:the specialization for two handed weapons should be +15% to attack chance with two handed weapons (just strait up not of original AC of weapon so that you eliminate the rounding issues) with either an AP reduction of 2 or an AP reduction of 1 with an additional +4-6 to base damage
AND
I think the dual wielder is perfect btw(aside from the rounding issues) and have some ideas for sword and board improvement but that is for a different post coming shortly
