User blog comment:Fistful of Force/Lane swapping: The forgotten tactic/@comment-5419795-20130201161445

Yeah, the stigma is part of it. But it can also be hard to convince someone to lane swap with you. Very rarely will someone want to switch into a lane that you have already lost. Their opponent will be ahead, and it won't even be their fault. So if they end up losing the lane further, they will end up blaming you. And if you lose the lane you switch too, everything is your fault and nobody is happy.

TL;DR Lane swaps work way better in an organized team than in solo queue.
