Hi - your link is set up as Protection geared so cant check Arms DPS gearing. Please alter.
Generally, please check glyphs - should have MS, execute, charge, in the mix.
Talents - need some tweaking - as Arms spec you dont have any 'Iron will' at all - please amend, ditch 'anger management', max out 'improved mortal strike; as you are 1 point short.
Cheers for now - Iraseren x
