So, Ranger/Warrior... any advice?

Read the Wind/Frenzy is working pretty well... good stacking... but any other skills or weapons or things of that ilk that I should watch for?

For a looooong time, this was my skill bar:

Frenzy
Hunter's Shot
Power Shot
Sever Artery
Gash
Troll Unguent
Comfort Animal
Charm Animal

Now that I have new skills, I have stopped switching between bow & sword/shield. Now my skill bar is thus:

Lightning Reflexes
Distracting Shot
Hunter's Shot
Power Shot
Watch Yourself
Healing Spring
Comfort Animal
Charm Animal

Edit: BTW these are strictly PvE builds - I haven't done any non-required PvP

I have found that an extremely powerful combination is Apply Poison, Sever Artery, Gash, then Final Thrust.

Start with your Bow, using Apply Poison + Skill of your choice. Don't stagger your attacks, simply deplete your energy. Apply Poison again as your last skill. By the time you are out, your Adrenaline is full, and you can close in with your sword set. Use your Sever Artery+Poison (Yes poison works on swords) to give them instant -7 Heath Degen, Gash to drop their max/current Health by 20%, then finish with Final Thrust once their heath drops below 50%. By the time you are done depleting your adrenaline, your Energy is charged back up, and you can take on the next foe.

I have had great luck with this in PvE. I have not tested this build thoroughly with PvP, so feel free to experiment.

Yes, but let's say I want to go the route of hammers. Is there an equivalent skill that reduces the health regen in THAT skill tree?
