The rage generation part is virtually useless, for arms you use thunderous roar anyway because it’s just way superior to spear, the bleed damage is just too valuable, so spear might as well be for fury only.
And the problem is: Piercing verdict is literally trash, the first hit does not do enough damage to justify taking this talent, and the rage generation is literally useless, it generates 80 rage, but you never wanna use it outside of recklessness, that means 160 rage, which is way more than the cap, and that is if you cast it at 0 rage, which is literally impossible.
I think it should just increase the damage of the initial hit, and increase your haste by 25 % for the duration of spear.
