As someone who sometimes types without really thinking and sometimes doesn't realise what they're saying, I think it would be fantastic if we could get some kind of a notifcation if our Honor progress has been slowed due to mild toxicity. It'd be helpful to help such players realise what exactly they are doing/saying and put a cap on it. I would not consider myself incredibly toxic - but sometimes I can just snap especially when direly tilted, so I think something like this could be very beneficial.
Ps. I won't turn chat off because I shotcall my team a lot. I do have the presence of mind to turn it off if I'm getting upset.
