combat advantage(CA) - You gain it by using certain skills while other skills consume it to be used. You need to understand how to use CA to maximize your dps and do well in both pvp and pve.
Devastating blow/Flawless strike - This is one of your 2 spam skills which you will use alot to generate combat advantage. You will want to get it r3 in most builds. (Generates 15 CA)
Charge - Gap closer which is not so useful in pve but generates some combat advantage. I took it r2 so I can get further in talent tree but if you can keep it at r1 and still go further than do it if you want so. (Generates 10 CA)
Lunge - This is your second skill which you will use alot to generate combat advantage along side Flawless strike. R3 is recommended for most builds. (Generates 10 CA)
Agonizing strike/Fatal Blow - One of the hard hitting skills for warrior. This will most likely be doing your most dmg or pretty close to Flawless strike. Consumes 50 combat advantage so you will need to use it after using Flawless strike and lunge couple of times. (Consumes 50 CA)
Die hard - You will need this as a melee dps you will most likely get hit by some aoe skills and also if you get aggro from mobs you won't die right away if your hp drops fast. I have it r3 for lower CD on the skill and needed it to go further in talent tree.
Intimidate - I have it r1 so if I need to take aggro of a certain mob away from a dps or healer or if tank needs a moment to heal up or battle ress. Pretty handy in some situations.
Adrenaline Buzz - Increases your energy regeneration by quite alot which always you to spam your skills more. R3 recommended for most builds.
Aura of Ferocity - Increases your dps and your party members dps. This Aura decreases your armor if you don't have the rubies for it but if you do get the rubies its nice to have this in almost every build unless you are tanking, R3 recommended.
Vicious spin/Whirlwind - Great skill for AoE pulls. Does alot of dmg on multiple targets and one of the few warriors aoe skills. R3 recommended for dps builds. (Consumes 65 CA)
Heroic Might - Gives you 3 stacks which will increase your dmg with flawless strike by a bit. Increases your dps by a small amount. Get it if you can.
Reasoned aggression - Generates combat advantage for as long as it is active but puts you in combat. Can be useful to use Whirlwind more often or use Fatal blow more. I recommend Heroic might over it but get it r1 if you can afford it.
Controlled rage - You need those so you can run ferocity without reducing your armor and making yourself more vulnerable to physical damage.
Verdict - Increases dmg dealt to the mob you use it on by 50/100% depending on rank for 15 seconds or until the mob loses 10% of its hp. Useful if you need to pass a phase of a certain boss quickly or need to kill it fast or to lower the hp of a boss fast so brutality can have a bigger bonus in dps. R2 recommended
Bushido - More energy is always nice
Get it if you can.
Peddle wall - Increases the shield amount of stony resilience by 15% and increases healing received. Its nice to have as being melee you will most likely get hit by some aoe skills or if you get aggro from a mob or get damaged by a debuff on an allod.

Arcing blow - One of the warrior's hardest hitting skills. The target needs to be affected by a knockdown skill for you to be able to use it. R3 recommended. (Generates 20 CA)
Forceful kick - Has 50% chance to knock the target down but to me it seems more like 100%
Get it atleast r2 for lower cd. Use it to knockdown a target to use Arcing blow on or just simply to cc him for few seconds. (Generates 10 CA)
Headbutt - Knocks the target back and after that the target is knocked down for few seconds. Can be used to knock people off cliffs sometimes or simply to push them away to charge them or using arcing blow. R1 is enough.
Ruthlessness - Increases your anger which will reduce the healing received by other people once you get wound complexity on them. Get them if you can.
Thumbs down - Increases the damage you deal by alot especially by Arcing blow or any other skills. As a warrior you have alot of knockdown skills so I recommended getting R3.
Swiftness - Increases your move speed by total of 30% after hitting a target 3 times. I recommended getting atleast r1 of this skill as in pvp it will prevent people from kiting you effectively and you will reach another target faster.
Crushing blow - Can be used as aoe damaging skill or gap closer. I use it mostly when I am blinded. R1 is enough but not a must have.
Streetfighter - Longer knockdown on Charge and makes it a 100% chance to stun. Really useful in pvp as with it charge can stun up to 4 seconds.
Unstoppable force - Cool name and makes you immune to any kind of CC while using charge. If used correctly you can avoid every kind of CC. Recommended in pvp.
Bash - I cannot go over how this skill is useful in pvp. First of all it applies 2 CCs, a knockdown and a 5 second stun which is pretty useful against bards as it will go thought ballade and every other class aswell. Can be used to knockdown a target to using arcing blow aswell. (Consumes 45 CA)
Knee shot - shoots an arrow that reduces target movement speed by 50% for 10 seconds. It is nice to have this one in pvp as it has longer range than your charge and can use it to slow someone who is trying to kite you. I prefer this over Hack as you don't really need to slow someone when you are in melee range as your swiftness rubies will help you stick to them once you get in melee range.
unless they stack willpower
In group pvp you can easily kill squishy targets before healers can react to heal them or you can CC someone while your group or raid kill them without your target being able to move or use healing skills/pots. You will usually hit hard enough for you to take kills (or killsteal
) and here is a proof of how good you can kill steal!
. It is another gap closer and works as a knockdown for arcing blow. Other useful reinc skills are tkpull and scout blink. I recommend using those for pvp but you can use any other reinc skill that fits your playstyle.
