Is there a best in show way to go for stats these days? Any updated guides out there? All vit? Whats the point of dex/str these days on a melee char, "Increases the base damage and *critical hit chance for melee weapons by the ratio for that particular weapon." What does this mean?

get more of the stat which is on the higher side of the ratio.
this means
all points str:
Swords/clubs
all points dex:
daggers/staffs
Doesnt matter where the points go (there is no point aiming for 50/50 either):
axes.

This means for barbs/fighters you should pretty much always go for strength, even if you use axes in your climb, there's a chance you might find a sword/club which is better than your axe for that level and decide to switch over.

Vitality is generally aim for anywhere between 75-85 if you're solo'ing.
