Have you ever...
Sat around an objective solo, pinging it and typing in chat this is the priority target to never see a teammate come close to you and squander the opportunity to take the objective?
Can we perhaps implement a warning message, similar to the AFK message that comes up (and perhaps links to "assisting enemy team" report as the AFK does to it's report) and warns you "You are not responding to your team. Please respond by chat or presence or you will be at risk of <insert consequence here>".
This could be set to, say, after 12 pings in an area without you responding in chat or entering the vicinity? If not, there has to be someone out there to have an idea on how to regulate this.
I am suggesting this for Ranked Queues only.
