Oh I have so much to say on this.
"avoid teammate' used to be unlimited, then they dropped it down to 3 because some bitchass Masters widow was taking 10 minutes to get matches, so putting it back to 15 is still unacceptable LONG AFTER it has been proven that this disproportionately harms lower ranked players.
Secondly, blizzard doesn't give a shit about cheaters besides appearing to do the minimum. They've had several big name streamers caught live and let them slide whereas I LITERALLY got a 90 day mute for calling out an obvious cheater in chat.
All of this is vapid bullshit trying to correct the franchise's nosedive from their disastrous OW2 launch.
