Cheating in PVP is so rife I'd prefer they just delete the game mode if they don't plan on cracking down and banning cheaters.

Besides the obvious example of add-ons, there's also the popular Discord groups that turn Frontlines into a win-trading cult of personality. I'd go as far to say that if you banned all the members of those Discord communities you'd remove ~80% of the cheaters, because the overwhelming majority of them cheat with add-ons too.
