ADCs top are made strong by the meta
Do you know why they weren't a thing in s1/s2/s3? Because duo tops were a thing back then. Because having to play Vayne top vs, for example, Sona+Darius meant either feeding hard or being level 3 with 10 cs at the 10 minutes mark. The introduction of jungling is what marked the decline of duo tops: tanky characters could hold the 2v1 decently while the jungler farmed and ganked, thus giving an advantage to the team.
Today? It would work too: I dare you to pick Vayne vs Sona+Darius and not feeding super hard. Why doesn't this happen though? Because the holy meta is now set in stone. Because even suggesting going duo top will be considered trolling and result in either a dodge or a 9xreport player, with the attached /ff before minute 3.
Alright then, enjoy losing to one of the easiest-to-counter strategies, you damn meta worshippers.
