Here's the thing
You shut down 1 lane, ok, ok, acceptable, assuming it's not something like Kennen or Jayce top against you, in which case, I'll report both of you for trolling.
Your team doesn't have a jungler, the enemy does, so even if shut down 1 lane uncontested, the enemy team can shut down 2 lanes uncontested, or can even contest you based on their top laner and your picks.
Bottom line is: duo top/mid is much more risky for far less reward than to play jungle, so it's not a viable strategy.
Funnel wasn't accepted, but that didn't meant it's not a consistent, low risk high reward thing. Your strategy is a high risk low reward that's also inconsistent because the enemy picks matter so much more than your own, and any strategy that requires the opponent to be bad, is a stupid strategy in 90% of cases because you have so little control over it.
