Trio and Duo. Helpful or Toxic?

I like to believe most Trios and Duos know what they need to do . For example, provide ganks to THEIR group and rest of team, speak to each other to HELP the Solo Q and, of course, stay grouped. One issue I am currently having is this Trio and Duo Group Mentality that shuts down the Solo Qers . I'm not sure if its on purpose or lack of awareness but it needs to be addressed. I've had multiple games with Trios who I would ping for help and they will continue to forcefully help their laner regardless if they can make a play or not . It seems like Friends > Win ? I don't believe that is correct. The worse part of the current issue is the Higher Risk of Unearned Ban. Trios and Duos are banning and making all the Top Tier Solo Q players at risk of losing , not only their match but account as well. We need to STOP the Overpower.
