I think we've all been here when people have left right in the middle of the game. It makes it very hard for us or the person that is left alone, it is not only unfair its aggravating, and nothing happens to the people that leave. I think we should have either a deduction of gems or shards or maybe both for who ever leaves, but under circumstances like a crash or bad wifi. The deduction should take place after 5 minutes because it will still give you time to rejoin the game, say as if you need to relog. What if it so happens that a new player decides to join? Their whole team is gone, that's not really the greatest first impression. I believe it should be 500 gems and 100 shards, it might seem a lot but it needs to be conveyed to the players that leaving is a punishment.
