In addition to nerfing Invigorating Shadowdust by 5 sec, we got also hit hard by the overall burst nerf (more stamina on trinket set bonus and less agility).
People have around 40k more hp (did blizzard even tested how HUGE lock shields now will be ?) which is like full cds eviscerate crit, maybe even more than that now because we have 200 agility less.
If we add this all together, our burst from average+ went to average-
Class which depends on burst got destroyed by this single change. We are now a stunlock and cc machine, back to old days. Thanks blizzard.
