Armor Lock is terrible, the fact you can gain health and shields while they're about to die, gives them a bit of an advantage, even if waiting for them, if you are shooting them in the back you are so screwed.
also, when you are beatdown someone, they use armor lock for a split second, take away all your shields and kill you, then tbag you. its so annoying
please get rid of it, the rest are ok (apart from hologram).
