Some people fail to understand the real point of the whole "meta thing": it simply represents the best way to play the game at a certain time, with certain champions buffed or nerfed, with certain items available and so on. It is developed by high level players thanks to their deep understanding of the whole game. This doesn't mean that under certain circumstances Sona can dominate mid or Teemo can support, yet a good result with meta breaking roles and champions may just be due to low level opponents or strong allies. Not to mention that even at a moderate level of play (e.g. Gold Division) you may have a really bad time with those unorthodox picks, since players are able to go for your weak spots.

I think it's highly advisable to promote the meta game and to let the meta breaking choices to those with quite some experience with the game.
