Now, outside of GreatweaponMastery feat(but that is a whole new topic and there is plenty of threads around on that already), two handed weapons are kind of weak towards sword and board, especially as the removed +1,5 str mod from 3/3.5e.
Even the fighting style is worse than dueling.
Take i.e. longsword 1d8/1d10 in two hands.
you get 4,5dmg one handed, 5,5 damage two handed,
If you have dueling style you do 6,5 damage one handed. one more than with two hands.
Even if you have both styles, two handed longsword will deal only 6,3 damage on average. Still less then dueling style.
So, suggestion is that Great weapon style adds +1d6 damage with every twohanded melee attack.
