Toxic? Chat ban. Troll ranked games? Ranked ban. Why are we mixing the two?
Because Riot considers trolling to be a form of toxic behavior. They also consider verbal abuse/harassment/chat spam/offensive language/etc to be a form of toxic behavior.
There are only two forms of sanction available for non-verbal toxicity at the moment: Ranked Restrictions and Time Bans. As such, players who troll, grief, or are otherwise toxic without using chat are more likely to receive a Ranked Restriction quicker.
Meanwhile, chat restrictions are explicitly intended to address verbal toxicity. However, should chat restrictions prove ineffective, future sanctions can be escalated to Ranked restrictions or even Time Bans, depending on the severity or frequency. It's important that these tools remain available for use in appropriate situations - as incentives, they can both be very useful in encouraging reform.
