I don't know about you guys, but for the most part I found this game pretty easy, but then I did everything I could before going to next part of the story. I have now beat it once on normal and once on hard.
-Warriors stats should be almost all strength I find. Vit is not that important and only increases health, while strength increases damage, health regen,and melee resistance.(also, dex does nothing for you as a warrior, unless you want to use a bow as well)
-I never made a mage or ranger, but I did make a warrior/mage combo my second time and that made the game even easier, even on hard. I went about 20 vit with somewhere around 80 in each of strength and intel I believe(can't remember exact choices).
Note: please don't dismiss completely DEX and INT as these boost other important stats Range and Magic Resistances, and INT boosts Magic damage and mana regen (INT boosts magic damage far more than STR boosts melee) whereas DEX boosts Crit damage.
Also you want to use a bow no matter what to open up with in encounters (it very very strong early game, and later is useful for splitting mobs up so you can take them on 1-2 at a time instead of all of them).
