There is no way to avoid this, but we are aware the community dislikes being thrown into on-going matches on a team that is currently losing.
The other-side of this issue is players reporting that they do not get backfill when someone abandons a match. Someone had suggested backfill for Ranked matches the other day, and I basically explained that this would be severely unfair to the Ranked player. since they would be getting or losing MMR for a match they didn't completely participate in.
I feel like removing this option may also make matchmaking longer. I do completely understand how underwhelming it can be, as it has happened to me a few times.
