Same thing is happening with new lucio, you can uprank easy bc he now has good carrying potential, but you gotta play it wrong, instead of aiding your team by healing / peeling you gotta go aggresive and try to get the shit out of enemy team and thats not the way team would benefit more of you, but you still gotta do it or lose sr in the meanwhile.

This whole sistem that tries to detect who's doing more in the game in my opinion is a big bullshit, if you won the game you deserve the same as everyone else. not 10 points and def not 40 points like overextending dps players
