Main skills for Warrior are Whirlwind, Rush and Jump attack.......stuff like bleed and fatality are a waste in my opinion, use those points in regen and reflect later,,,if your potion dependant toss a couple points in potion...
Regen and reflect is totally useless skill. When you had high str with accessories healing aura, you basically wont need it. Potions will save you in critical state but not regenerate. As for reflect, when enemy doing mosquitoes bites on you, what you reflect back is basically mosquitoes bite.
I not sure if you had try out bleed in high rank or not, but you can easily notice it by same old bunch of mobs suddenly die faster as compare when without the skill. But its not a must have, rather as recommended to have. As for fatality, it more on personal preferences, same goes to rush, jump attack and whirlwind. I hardly use jump attack myself, since there is no need for doing so. Thousand strike is good for 1 hit ko bosses, like final boss Divine.
