Main Sadira, and the hate messages will hit Max Level.
In terms of getting angry. I once uninstalled KI and hid the entire game in retaliation to losing to a (at that time) known lag switcher. The guy was a total troll and very good at what he was doing. I ended up playing the guy 4 times in a row. He taunted and teabagged between each lag. I had reported him and blocked him after the first match. I had believed that I could still block people. Nope. It was trash. All the work I did lost to a cheater.
I then learned that you couldn’t block people (something I still believe is wrong) and it hacked me off so I uninstalled KI. I didn’t come back to it for a week.
The only other time I got really salty was when I got a KI bug after the Aganos patch that caused my stats and Rank to randomly reset. I was literally having to requalify every other day. I’d just get back to killer and BOOM, back to Qualifying again. I uninstalled KI and wrote a very hot letter on the message board, as before my little triad it seemed like none of the staff would respond to my reports. Needless to say, they reached out to me, and sadly, I ended up having to completely wipe all of my saved game data taking all of my Level 50 characters to 0 and I literally had to start over from scratch. I lost my Platinum KI symbol for completing all trials in S1. I lost the complete S1 story mission poster and all my S2 progress. Needless to say, I didn’t touch KI for nearly two months after that one.
Honestly though, if I’m really getting frustrated, I quit playing. You should never harm yourself over a game.
I’ve banged on my fight stick with my hand a bunch of times, nothing too major, just on the wooden part like “Oh FFS!” thump
…Usually followed by a swift slap on my arm from my fella shouting at me to not hit a £150 fight stick in case it ruins the contacts, he is of course, correct, which is even more frustrating as I really annoy myself when I do it anyway, but it just comes from being caught up in the moment. However, I’m not throwing controllers across the room or anything.
