If you're tanking I wouldn't suggest this at all. ACC is amazing I'll give you that, but when tanking you don't want to just be sitting there. As we all know, currently Regiments are clunky and while being involved in one you cannot do any other actions. So while you're waiting for your group to get your BR done you're potentially losing hate and if it works like XI, whereas you hit a cap and start decreasing, wasting time on this could potentially kill someone if they pull it off you due to your hate dropping.
-OP
Your build is decent for soloing or grinding I suppose but you're using so much AP on WS. If I recall correctly you had 4-5 different weapon skills listed and one of those was riot blade (5 points). Honestly outside of phalanxII and maybe 1 reaction WS's(fracture/jarring/feint), we only need 1 real WS(depends on fight, ie Incap WS's) unless you're short handed and you yourself need to be pumping out a lot of deeps.
As others mentioned atk+ modifiers(raging,ferocity), generate decent hate with zero stam cost which is a definite plus. I lean toward raging more then ferocity because of the 30sec CD.
Although missing is annoying apart from that, its not that detrimental to land your hit. Most of our hate comes from abilities not damage(aside from heavy stab/phalanx), so prioritizing DEX over STR(increase block dmg) I don't necessarily agree with.
Hadn't seen anyone mention it yet but accomplice(pug 30) is a nice lil hate boost also with a decent CD and can rotate it through your more damaging DD's / healing mages.
