Toxicity is already a problem with normal skywars as there are people who canāt even handle an unfair loss (as if the game was actually meant to be fair after all). I see people constantly moaning in chat about getting void knocked, cleaned, 2v1ed, outgeared, had speed or apples used on them, or even because they were killed in the beginning. I can assure you that every PvP gamemode on any server is a sea of salt. Ranked skywars wouldnāt make much of a difference in terms of player chat behaviour (and you could always mute the chat, for any gamemode). A bigger issue would be cheating, which could be reduced significantly with a good anti-cheat and by only allowing people to participate in ranked once they have reached a certain amount of wins in normal skywars.
