On over picked champions, and a proposed solution.

So i've really been seeing way too many of some champions, and not enough of others.. for example i can't remember a single game in around three months that didn't feature at least two of either Katarina, Sona, Soraka, Vayne, Lucian, or Yasuo in each match.

So I was wondering how players feel about the concept of a system which lowers prioritization of over played champions, and an option for team builder captains to "refuse mirror matches" in game.

i don't particularly think many of the over played champions are over powered, and i don't believe that they need nerfs, but i do feel sick to death of facing yasuo every game, and I rarely see certain champions that aren't particularly weak such as vlad or aatrox.

so yeah.. anyone else have thoughts on this?
