User blog comment:Chase999/A Ridiculous Team Strategy/@comment-15244341-20140602104928

It used to be done with Vayne quite a bit. I believe in LCS even. Don't really know how it worked but it always sounded effective to me if the carry was any good. Also, when my carry is super fed, I peel for him or her in teamfights no matter what (unless my champion is uncapable of peeling). This is something really important for toplaners to do, actually. If your carry is the reason you are winning, you should peel. Period.

That being said, this is a legit strategy in Dota2, in which 4 active gankers or 3 gankers+1 babysitter make sure a superhardcoremegaxtreme lategame carry farms his/her ass off for 40+ minutes by constantly disrupting the enemy team. When the carry gets six-slotted they proceed to murder everything in sight (see Medusa or Anti Mage). This is however pretty hard to do and not as spectacular as team wombo combo (of which there is an awful lot in Dota) so it isn't that popular.
