You know how you deal with toxic players… Ignore them… and stick them on mute and block. You dont have to listen to them or see what they write, listen to what they say. The power is in your hands. Its like if someone in IRL is mocking up you can just walk away. You give toxic people power by listening and responding to them. If you cant handle getting in the mix with those sorts of people and cant hold your own against them Ingame then my best advice is dont engage with them at all…
Personally its always fun to take down the blowhards.
