Why are pink players allowed to queue for ranked? I don't think it's a major concern for random battles and co-op battles, but when someone queues into ranked with the goal of disrupting their team's gameplay by ramming, shooting, and torpedoing their teammates, I don't think the automated system is enough as it is now.
I was teamed with a Schors in ranked that did this. Although the restrictions placed on pink players prevented me from taking excessive damage, it still effectively took me out of the match for several minutes, and the Schors did nothing that helped to defeat the enemy team.
Is there any point in submitting a ticket and replay to Wargaming?
I think blocking pink players from queueing for ranked until they have played the necessary games in co-op and random battles would be a significant barrier to the few players that might attempt to purposefully lose matches in ranked battles, and I don't think it's unreasonable for players that accidentally cause damage to friendly players.
