Ranked Mirror Matches
We see the same champions banned every game, and the same champions picked. Worse, we see a team get completely shut down if someone forgets to ban champion X.
Instead of just having no chance to win, or having to pick an unfamiliar champion that counters the one they got but you wanted
We should be able to pick mirrors in Ranked
It's not a test of skill at all just to know who counters who or who's OP right now. If both players get X top, there'd be no reason to ban him, and the bans could go towards actual strategy instead of just whoever Riot decided to give a massive buff to. Then it'd be down to who's better with X and which jungler was helping more, instead.
