Hello MasterMiyagi15
This happens to me and a lot of others very often, and we have brought it here. Unfortunately, there is no recourse for us, as apparently the system can't tell the difference between a voluntary and involuntary disconnect. I saw that they are employing a new system in online multiplayer matches that considers situational factors, hopefully they will bring this to squad battles in some form. There would be no reason to quit while winning squad battles convincingly, even for an (emergency) you could just hit pause since there's an ai opponent. As a player who reaches elite 1 so easily that last week I did it in spite of 2 disconnects and a rare loss (no details needed), I have been pushed down to elite 2 or 3 multiple times, so I feel and understand your sentiment.
All the best to you!
