I've always loved the warrior build when playing MMORPGs and single player RPGs, but Divinity II is proving to be quite unforgiving for my taste.
And I have to agree with Zerael and Sadiablo. Warriors are unstoppable, but in order to be a great warrior, you have to go through a slow and painstaking process to get to where you need. I reached level 23 and I BARELY felt the benefits of my extremely high VIT and STR.
