Intelligence is about the only stat you don't need for a warrior, scarily. Agility affects chance to hit, Speed affects hit rate, etc...
I put two points into Str per level, and one in each of three other stats, keeping them roughly even as I went up levels. My fighter thus relied on doing a lot of damage, but his other attributes were not terrible.
I started with one-handed slashing, then changed to two handed slashing later in the game, as the damage on 2H weapons is significantly higher. There are a fair number of very good 2H swords and axes around, and only one decent 1H sword - at least that I found!
The benefits of using a shield - to me - are not sufficient to justify the damage loss. Especially as my Mage was a walking potion factory! <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
