I agree with TR_8R but perhaps for slightly different reasons. 1) The banhammer goes into effect after 1 match where someone leaves. i know this b/c it has happened multiple times to myself and others that I play with. That being said, 343 promised that we wouldn't be entered into matches that had a) already begun and were not full. I can say on numerous occasions that on Warzone "a" has happened and on arena I've had to play with 1 or perhaps 2 others vs. a full team and once realized that it is a losing proposition I leave. They really should follow through on what they promised us originally instead of handing us a hope that they had no intention of following through on.
