Hemo bleed is complete trash like live. However it can crit again so more chances at hat procs.
Everything sub has does trash dmg but rupture and evis. Basically they took dmg from sv, backstab, and ambush and put it in rupture.
For some comparisons live rupture scales with 74% ap(148% if account for the ap changes) beta rupture 672% beta rip 535% to give you a better idea of the dmg differences.
