By looking at your armory, I have a few suggestions on what to put your points in.
-Finish off Weapon Mastery with the next point you get
-Put two points in both Second Wind and Blood Frenzy
-Max out Improved Mortal Strike
Endless rage wasn't an extreme need for me, although useful, I think your points could be spent better elsewhere.
Now, a good bit of points if you stay dps will go into the fury tree after you get what you want in the arms tree. However, I'm not an expert at the fury tree for I was arms when I was leveling.
Hope this helps!
