I'm a developer myself(not in rito games), I know it's stupid vibe coded game.
Basically when your teammate equips an ability there is a voice line loaded in your computer but if he spams q-e-q-e 100 times in a second using a script or macro it fries your CPU and your whole teams fps goes down, looks exactly the above attached video
It could be just solved by a client side rate limiter
Also he is ain't afk technically so can't even surrender
(Sorry English is my second language)
