I build around Kinetic Carbine and she is consistently the most fun champ for me to play... Very easy to get a solo kill for me. I often 1v2 as well. So please don't change her like this! i think shes great. The wall and pull is a bonus but not the end goal. You can do massive damage and lock...
Had a few bot games with Yamato where my crosshairs left my screen and i was unable to shoot. Seems to be when i get CC'd or get off ziplines near enemy base. Only had it happen near or at enemy base. Using my ult has fixed it each time. Theres also a tooltip telling me i can press space to abort.
