Bonegrider - 5 stacks to make it work is too much. You’ll never get 5 stacks even with Obliteration guaranteed crits so basically its useless talent that needs 2 point in it.
But there is more, next talent in a row Cold Blooded Rage is useless too. 2 points to get 20% chance per frost strike critical strike to get killing machine? You’ll nearly never see it proc. Another 2 points wasted.
And thats only to get good Obliteration talents which costs basically 5 points.
