Oh, Rupture, not Pulverize. Just looked it up.
I think you should give it another chance. Only 10 sec cooldown! Even if you totally ignore its basic function you still get the AOE bleed and +20% attack speed for 4 seconds. That means 40% of the time you have that attack speed which effects every skill. 20% more bleed basics, etc.
I think it's a skill a lot of people sleep on. Same with Lunging Strike, which also works OK for a bleed build if you pick the bonus bleeding damage passive. Still not as good as Flay.
It also has a 50% lucky hit chance, which is quite high.
