you get all the gear you need with the quests.
main dmg skill is slash,
Defensive to Offensive is very usefull
after you hit lv50 you should decide to go AoE or single target,
but you get endless TP so you are able to max all skills- AoE+single target
dont upgrade anything till 50/xx, expect maybe tier a T1 or T2 weapon to T3 (not needed, but speed things up)
stay on one weapon type, since your skill increases while you use it.
1h axe+shild or 2h axe (some AoE requires 2h)
stats you need will be: str/phys attack >stamina >>dex
dex got more important, since you get some combo skills, and if you dont hit once you got to start your combo again.
Im playing Warrior only as second class, Im shure there are other opinions out there.
