This is all very well researched dude, very good.
Everything I’m about to say is based on my own experience of KingUsha, as I’ve played vs him randomly since injustice 1. He is a super sketchy dude that even takes random casual online games super seriously, to the point were he has lost to me in MKX with Kung Lao, and before the second game can begin I will have received a message saying “only started using KL”, of course, upon checking his character record, it turns out to be his number one character, so something like this wouldn’t be out of character for him.
When you said KingUsha. I wasn’t surprised.
No doubt he will have other questionable Russian mates on here that will try and vouch for him simply because he is Russian so are they. I think
@stosn has already tried to defend him, of course, without reading the ESL rules before doing so.
