When it comes to balancing champions in competitive play...

The statistics are all accessible to the public. Probably not as in depth as the statistics Riot has, but enough to tell us the simple matter of who's good and who's bad. There's always outliers on both sides too. But what I don't understand, is why the patches never really seem to have full correspondence to the plain statistics that we can see day-by-day, month-by-month, patch-by-patch.

It bothers me how this game has SO MANY champions, but only a select few are common in ranked. People are always going for the OP carries that are not banned, every single game. On the other hand, the sad champions that use to have their name in the spotlights are now never seen.
