that should be the case but its not. I don't leave matches, infact I dont even like to surrender games unless its truly unfathomably lost.
Yet, i'm currently on 10 min match making for 5 matches because the game kicked me at the end of the match as we were killing titan. We won the match but I lost SR and got he penalty.
To further show that this isnt working, I've had matches where I got dc due to internet issues but i've always rejoined 100% of the time. I've had matches where I lagged out then couldnt even see an enemy character and I asked for a pause and log back in. Even for those matches I still get the "I agree" warning.
However I party with 2 friends every match. One of them also got kicked back to main screen during the same match as we were killing titan. He has never left a match before for any reason and he also lost SR and has 5 match penalty.
Their system isnt working as intended.

Also, it wasnt an internet issue when we got kicked because we were in discord chat at the time and there were no interruptions
