This is a very good build for a warrior that likes to focus more on the offensive side of pvp. It isn't the best build for support, but I would suggest using this combo if you are more of the type that goes out for blood, if you now what I mean.
Sometimes I switch my skill slots to bull's charge and endure pain for 7 and 8. You can switch those up anyway you want to but frenzy seems to help out a lot. And also make sure you have that signet of rage on your axe, or just any weapon you are using for that matter. Whenever you happen to hit that 10%, ur just like thank god. Ever since I switched to this combo, I have been doing atleast 10 times better than when I was using GS/Rifle. Being able to switch to a shield helps a lot, I like to use when I need to get a feel of where am I at and whats going on around me (crowd control). But yeah, I freakin love this build. Found it from a guy on another forum.
