Now that you mention it, some guy recently in one bg was using the anticheat to his advantage. Every time he took flag and tps all over the place and gets ported back, does it so often it was nearly impossible to even land a hit on him. So in a sense, he's just able to troll the enemy team into running back and forth constantly.
Yes it kinda stops them, but it doesn't hurt to make a report about them. Then you got the exploiters with their damage stacking and or instakilling of players.
