Sustained rage does not add much in the form of aggro lol, just DPS.
There is a reason guardians are like 22nd on DPS list but always #1 on aggro list.
Get rid of prowess/brutal blows, and take out ALL the points in bleeding counterstrike/bleeeding dulling blows, maybe put 1 in bleeding dulling blows.
Then put points in stand your ground
Then obtain goad/Cunning deflection in the general tree and you are G2G.
Something like:

Then put your points as you level in the intervene/juggernaut line.
