Well I agree with this- why not an option to turn it off for everyone who want to avoid toxic people there?

Arena is stressful place and some people can't deal with it and gets angry too easy then let it all go on chat~~ there are also people who are just that bad in general to insult and make fun of you simply because they can.

And then there are those who just makes you laugh with hate attempts. "you **** whale- stop taking money from mommy!!1!!1" (me looking at my team of mei, yagura, han and complete lack of medal or anything and being the said mom) "ok :) "

Anyway, for now it's best to just switch to other chat and/or don't think too much of anything they say there. You don't know those people and they have no meaning in your life- why would their hate should?

Or reporting them if you have time and want to but... I also believe that some serious changes about punishing toxic behavior would make all them feel less like "I can do whatever I want and what you gonna do? report me? hahaha they won't do anything anyway :D"

Side note- my battle chat is disabling on it's own a lot recently- why doesn't it happen to toxic people, I ask xD But anyway- to that person who talked to me yesterday during matsuri- I'm sorry luv T_T I wanted to reply but chat was like NOPE.
