If you were to watch the matches you would see Sado performed very well, and was on par with the top tier main tanks in the league. But I know that is too much work for you.
Do you get money for your d.va bombs? If yes, than you are pro, if not, than not. This is the definition of a professional. The number of kills does not matter but I think you would even struggle with these in the same matchups. There is a reason these guys are paid stars in this game.
