PvE Trait Allocation
the meta 30/25/0/0/15 glass cannon build should be your starting point. if you can’t handle it try to get survivability from gear (so slot in knight helm/chest/legs and berserker everything else) while you try to get used to it.
if you really cannot handle the standsrd build (which shouldn’t really be the case since warriors have so much durability) and want defensive crutches like adrenal health the best dps build you can get with that is 30/25/15/0/0, but loss of some traits will be noticeable.
if anything just try to get more experience with your class running an optimal build before going full tank kitten which reduces your usefulness in dungeons.
Use Signet of Stamina, with that you can dodge 50% more often. “Shake It Off!” or Balanced Stance to have a stun breaker can also come in handy.
For weapons I advice Axe/Mace and Longbow or Rifle:
Axe’s auto attack deals good damage, Axe #3 is a ranged cripple in case your foe runs away or you want to gain some distance, and Mace #5 is a knockdown which can give you a few seconds of breathing room. Both Longbow and Rifle have skills to keep a foe on distance or blind them so they can be useful when you have troubles staying alive in melee against a foe.
You’ve made the right choice regarding traits, but 10 points in Strength for Power and Two-Handed Mastery, and 10 points in Arms for Precision and Deep Strikes; you properly will be using Healing Signet, Signet of Stamina and Signet of Rage (elite) so it should boost your damage quite a bit.
In my experience the typical PvE Warrior (meaning: no bunker) is actually quite squishy because you hardly have access to skills that help you stay alive; you could give Endure Pain a try as your third utility but I wouldn’t trade it for Banner of Discipline. Basically you have to kill your foe faster than it kills you and hope nothing unexpected comes at your way.
