Starkiehow does it make you drop people in ubers?
From my experience: if you don't place your crosshair correctly, the beam will go to the first person available (especially happens if you're holding down m1) - and if your teammates' models are inside one another, then they are at risk of being dropped simply by not being flashed.
Unsure if that's what miwo is talking about, but I hope it helps.
