I accidentally had it glyphed for a few attempts and it was really disorienting. Also, it's hard to catch back up once you get ported backwards... although you can shadowstep through lasers so there's that, but that seems like a lot of lost time. I try to line up my KS usage with when the weapon I'm killing will be going through a center opening (or just pop cloak + KS right before going through a laser). For example, we kill mines on first belt, which is the second weapon that comes out. I can get up revealing strike, slice and dice, and then pop KS. The opening in the first laser is in the center when the mines pass through it, so after I killing spree I dont even need to move--typically that weapon is dead before the second set of lasers so then I'll just pop sprint and jump off at the center.
I typically use CoS to get through the last set of lasers. Sometimes the last two sets of lasers, but you have to run infront of the weapon you're killing at some point because CoS is juuuuuust long enough to make it through two, it's safer just to run forward a bit after you pop it.
Also a note: we were playing around with kill order during progression and we tried for a few attempts to kill an electromagnet. DO NOT KILLING SPREE AN ELECTROMAGNET. I think the size of it bugged out the ability and it would port me to the weapon before or after it (and no, my cleave was not on)
