Some people in this community need a reality check. Stop making personal attacks in people's private messages just because you're upset over a video game. It's cringe. And it's usually the same people that do it (Arbalest/Lorentz Driver users) and it's getting old. Little man syndrome, other wise known as being a keyboard warrior, isn't the play. Humble yourselves.
Sorry it is a truth that today sad people will complain and send nasty messages if they don't like something be it..
Losing a match.
Item or loadout used.
The worst game for it is COD which is one of the reasons I stopped playing it.
All you can do is if the message is nasty is to report them on the platform they messaged you on and then block them.
