First of all you're 26 level. You're not even a Bronze player. I think you shouldn't use terms like "Bronze logic". Try to get out of Bronze first.
You said nothing about how you were acting in this game. If LB had hard lane why you didn't help her?
Lets image LB was rekted so hard, so it was better do no gank midlane. So you had one lane less job, did other lanes were super carried by you then?
I dont't know what you were doing this game, but if lane losing it's jungler job to help it. If lane lost pretty hard, it's jungler job to babysit other lanes, so they could carry that game.
Bronze logic - it's when people writing "SOLOQ" or "play for yourself only". It's teamplay game. And fault of one lane is a fault of whole team.
When people say "why are you asking jungler for a gank? enemy jungler didn't gank you, so you have to win your lane by yourself!", they're just showing their rude and lazy nature. If jungler seeing that his teammate is dying and enemy is going to base with 1 hp, this jungler must think about what an opportunity for a assist/kill he's just missed. Sure some people will rage if their jungler can't understand so obvious thing.
So man pls stop doing this LB's mistake and try to review your own game. Can you honestly say to yourself that you did everything to help LB and other team? If yes, then ok - you're right. If no, pls don't write such topics anymore.
