I'm a warrior and i'm going with 10 points in vit and 20 points in str
As with a War u get defiance which increases ur hp by 25% but lowers dmg by 25% so you already have this huge hp pool but now require some dmg.
Str also increases the amount of dmg u parry so could help a lot with survivability, although the rate in which you parry is increased by DEX that stat is only really useful to archers/bards.

You could mess around with DEX though could be useful to pallies to increase there block rate then have them equip a shield with High dmg block but that's might be better for end game stuff.
