Relentless W/R and Pet

Hm, MAXED hammer mastery and no hammer skills?
hm....

What kind of build is that? Even in CA, the ONLY 'self-heal' I bring is an anti-hex/condition skill. No warrior can beat a damage oriented team using some piddly temp max hp boost and some e. required heals.

No hammer skills at 16 hammer? No damage.

No 16 BM means no damage either but you should at least run 10!!!

16 hammer, 9 strength, 10 beast

With that hammer setup, I'd DEFINITELY bring Devastating Hammer {E}. Hands down.

Your pet should augment your damage a little. But JUST a little.

For that build, I'd make it like a combo of 2 warriors moving in for a tag team beatdown. Since pet attacks NOW behave like shouts, the W/R beast isn't as shitty as it used to be.

Consider this:

Devastating Hammer {E}
Crushing Blow
Hammer Bash
Irresistable Blow
Maiming Strike
Call of Haste
Comfort Animal
Charm Animal

No room for a res sig, which is what's going to happen when you bring in a pet. Maybe ditch comfort if you're sure your pet won't get toasted.

Instead of yourself bringing Frenzy and Sprint which only last for so long, using the pet to keep up with your enemy and IAS is fine. Maiming has a nice duration and recycle time so worrying about feeding it energy all the time isn't a problem.

My gripe is that Ranger has NOTHING that can benefit from warrior knockdown. [and no, switching to bow to use hunter's shot after a hammer KD is just stupid to the max...]

I personally would run an Axe warrior using Evis + Axe Rake for a 2nd chance to cripple. Exe Strike is hot too.

5/1 Vamp means you lose health over time. Usually people bring mending. Or smart players only equip their vamp weapon once battle starts.

Anyhow, KD ranger+pet interrupts works pretty well for me, as long as you keep spamming mana skills (irresistable and crushing blows, bestial pounce and disrupting lunge) reversing classes to get to expertise might really be worth it.
