Hey there! So i've come to realize jump+boomstep is a dificult to execute. I love to grind with my Shad, thats why this annoyes me a bit. Maybe it is meant to be that way so we dont have higher DPS in specific bosses? Not sure, but i would love to know! Or maybe we can get it fixed :3 Thanks!
So that they buffed the height and width of bommstep on recent Shad buff. If you find it hard on grinding , try jump attack ( click jump button and bomstep button at the same time).Hope this will help you abit. For the real , in zakum you can attack 4 arms at the same time, hero and dk cant do that.
