Better punishment for those who quit rankeds

I think its time blizzard adjust their punishment system especially to those who quit ranked matches. Im talking about my ranked life but I also think Im not alone in this, its fucking tiring and depressing to keep losing a great amount of points due to these fuckers who easily lost hope in the game and quit.
And also some way to help when a teammate got disconnect or quit like putting bots in their place would at least help. At least while they`re trying to reconnect or something.
