To be fair. Those were private matches amongst “friends.”
I don’t think it be rage quitting if you are disarmed. It’s more rude and waste of time for everyone.
I can see someone quitting after a disarm. If it’s amongst friends.
I personally wouldn’t quit even under those circumstances for obvious reasons like your friends aren’t your friends they’re recording every single thing to use for later, if you get out of line.
If you quit under any circumstances in pubs or privates vs someone who’s not in your immediate friend circle It’s rage quit.
