I played today a match against a very suspiciously moving Zarya. I saw set moving patterns when moving and strange overall playstyle.
1st round AN54X8
2nd round 1RFMCR
Player name: Stalinwolf
I watched the match afterwards and Zarya had a kind of similar pattern when leaving spawn using all ammo to rocket jump from spawn, then when Zarya enters point it starts doing this C-Movement pattern while doing damage. The aim is very robotic and when Zarya dies it starts to spasm weirdly. See for yourself!
