That is the wiki page on stats but it has misleading and wrong information concerning warriors / p99.
Warrior specific info:
Strength: of secondary concern, but it does affect damage and your ability to stay unencumbered. Don't put starting points into it as a warrior. Your job is to take damage, not to dish it out.
Stamina: converts directly to hit points, very important stat for warriors. 10hp per stamina at level 60 I think. non-ogre warriors usually put all of their starting points into this and for good reason.
Agility: agility gives you AC at a low conversion rate beyond 75...as long as you have 75 agility, don't worry about your agility.
Dexterity: very important warrior stat. It affects the rate at which your weapon effects will "proc". Warriors use weapon procs to generate agroe in this game. As a tank class, generating agroe is important. Ogre warriors usually spend all of their starting points on dexterity.
Int/wis: whichever one of these is higher will determine the rate at which you level up trade skills.
cha: Affects how much money merchant's will give you for your goods. It also is a factor in the success of the spell Divine Intervention. Which will give you a second chance at life while tanking a raid boss. Not many people seem to actually worry about this in the end game though.
