Arms PvP
People have to understand how a warrior works before they can complain about it.
First we must note that there is 3 things that make a character good in PvP.
-CC's
-DMG
-Survivablity (heals, last stand, BoP, Pain suppression, immunity to stuns etc.)
For survivablity, warriors are average. We can use shield block against melee, Shield wall against all classes, Disarm and spell reflect. As well as enrage regen. Shield block isnt the greatest defense because there isnt many classes that melee. Even then they can stun you and you cant block when ur stunned. Enrage regen isn't really a good move to try and save yourself when at 25% health cause it heals over time.
For CC's warriors have very very little. All warriors have is hamstring which is only a 25% chance to immoblize the target (Nothing close to Chains of Ice from a Dk). As well as a 2 minute fear which isnt bad. When comparing to druids, mages, rogues, DK's, warriors CC's seem almost laughable.
DMG is the only thing that makes a warrior good. Even the idea of a warrior is to be a high Hp, armored and damaging class.
Overall warriors have almost nothing for CC's, shield wall for that one time save, and DMG. If warriors damage is removed you are left with a useless character.
Also note that if you get a new item that reduces melee damage by 5%. all melee will lose 5% DMG except warriors who will lose, this is a guess, 7%-10% because of how the rage mechanic works. This also means that if rogues get an item that gives 10 agi and then another 10 agi and then another and so on. He will get a constant increase in DMG while warriors who get 10 str and then another will get an exponental increase in dmg because he will be getting more rage. More rage -> more dmg and vise versa.
Inconclusion that means that warriors are very gear based and is effected greatly on opponents gear and our own. We have little CC's, Average survivablity and good DMG. Damage is the only thing that makes a warrior function as a good PvP class, if u nerf it warriors become useless.
