Great maturity you're showing there, how long did it take to think up that one? Kinda seems to be like you're just an unlucky Support (Jungler would be correct, by your matches) who's had a couple bad Bot Carriess today and assumes that, disregarding past experiences, all Bottom Carry mains are eeevil, and you don't want to plaaaay with them anymore because they're so meeean.
Don't get me wrong, sometimes it is the Bot Carry. In a lot of cases, thanks to our bullshit Dynamic Queue system we have instead of Solo Queue (which by the way is officially never coming back), it most likely is that role that fucks up, and nothing's worse than someone with a Top mentality forced to go Bot Carry and gets blamed because he knows more how to play Trundle and Gnar than Ashe and Vayne.
Guess what, though? It's not always the Bot Carry. The weakest link of the team is what keeps the team behind, and Supports, Junglers, and the other lanes are just as capable of being complete pissants as a Bot Carry can be. Tbh, Supports are more likely to do badly because all other roles are offensive while Supports play defensively (supportively, if you disregard that it's not a legit word for some reason), therefore those not used to playing Support do worse than they should.
The lesson here, don't blame the Bot Carry; if anything, blame yourself and be more of a teammate with your team instead of blaming others. Even with your consecutive Ranked defeats, I assume that you're a Jungle main and should be able to realize that perhaps you're just not doing well at Jungle and should improve on your gameplay and teamwork instead of whining about how your teammates are bad. Though tbh again, if I were to make the same stereotypical assumptions about a role that you're doing: I've seen Junglers with the assumption that they always get blamed for the Laners' faults, to the point they end up blaming the Laners for this-and-that instead. Junglers should be good at teamwork, but Tilting is especially bad for them because the Jungler is more likely to feed their opponent than the Laners. Junglers like to quit, or at least perform like a sloth the whole match, when the Laner next to their first monster doesn't Leash them; they're also known to knowingly steal kills when ganking, for any number of reasons. Need I go on?
