Why do i lose so much SR when someone leaves the game

why is it when one or two enemy players leave the game i gain no SR points(i gain something around 6) but when my teammates leave i lose 26(literally happened to me today plus i had a bronze in my team even tho im a gold rank) can someone please explain why that happens,i get that average team SR determines how much i will gain or lose but its just ridiculous that i lose points because someone left and if its something simple like this game is just like that than i guess it is


Lord Jeff giveth and lord Jeff taketh away. In all seriousness tho, it’s faqed and the how comp is managed as a whole is kinda of a joke
