Nobody ever mentions you losing to SK in a negative way. You simply lost to SK and that's how it goes. People were mentioning that when coming up with the player tiers or w/e because it's something they can use to compare players. it's not like they were all "bane sucks, lost to SK lolz"
Besides, that's exactly the same as you saying "how well i recently do vs isai." Isai might argue that you wouldn't do anywhere near as well irl because online has delay.
You're a great player bane (one of my favorites to watch). Just ignore the people who brag about nothing and keep playing.
