I finished the game a few weeks ago, but I might still have a saved game with my warrior from Act 3(or at least from the end of act 3). If you're interested, I could post his stats later tonight when I get the time.
Strength is important to a warrior, but Agility and Constitution are almost as important. Be sure to assign enough pts to agility to improve your weapon accuracy and to gain better defensive abilities. If your warrior can't hit the enemy, it won't matter how strong he is. A high constitution will provide you with more vitality and more stamina, and a higher resistance against poison. I would assign more pts to speed than survival for a warrior. Having a high speed and high initative allows you to get in the 1st attack, and have faster attacks, which is always good for a warrior. I would put more pts in Survival than intelligence, though. Warriors don't usually need alot of mana. Unless, you're a warrior/wizard combo.
103 luck at level 20, that sounds ok. At level 49, my luck is around 155. Supposedly luck will allow you to find better items in the game. Personally, I never paid much attention to what items I was finding in relation to my luck rating at the time when I found them. So I couldn't tell you if the luck rating affected what items that monsters drop and or what items that you find in containers, but I'm sure that someone here might know the answer for you.
That's enough ranting from me, at least for now. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
