Primary warrior skills? Probably just Frenzy and 1 hd Weapon Mastery are key. When you are on your W/R you will mostly just be shadowstabbing everything anyways. If your SS doesn't kill things, well you go with Probing Attack/Open Flank/Thunder. General skills Brute Str, Berserk, Whirlwind, and Slash.
Weapon combo can be either dagger or axe in any combination depending on what you have available. Most of the higher level R/W's or W/R's you will see will have two axes.....because they can. Daggers are faster but do less damage, axes are slower but do more damage...in the end it comes to DPS, go with the higher DPS. Note that R/W has an elite skill that boosts their 1Hd axe damage.
