Actually crushing blow is not nerfed at range, it just acts in 2 time less:
1/16 on bosses
1/8 - on other monsters
the same with open wounds.
with gore riders you will have 50% crushing, 30% deadly strike.
using guliame face + atma scrab +gore +faith MB I kill hell baal in 8ppl game in solo in 40 secs. Who faster? I believe that crushing blow do the job here.
