The only way to carry is if those on your team aren't deadbolted to the floor
Your teammates need to at least have the brainpower necessary to allow you to carry.
That means knowing how to itemize correctly, that means knowing how to watch the map and be careful in no-vision areas, that means knowing how to group and defend objectives instead of fucking farming nearby camps and accomplishing nothing.
I can't carry dumbass supports that insist on building
into the ADs they fed.
I can't carry idiot midlanes that build 0 defense period into enemies with high burst.
I can't carry dumbass ADCs that refuse to play and build defensive and work with the jungler after they fucked up already and gave the enemy a lead.
I can't carry moron junglers that have no inkling of how to so much as assist lanes instead of running into the unwarded enemy jungle trying to get that extra unnecessarily risky farm when the enemy is in a perfect position to collapse on them.
No one can carry with conditions like this.
