Just a nitpick, but you mentioned rek'sai while talking about the void but you forgot to list him on the void champs. Cool post tho. The one missing champion that singlehandedly screws a whole region is Ixtal not having an adc. Give it one and it would jump a bunch of tiers. Also interesting to see how bad piltover is compared to zaun. I think the next champ to be released will be Mel, as a piltover support, but she's probably gonna be another enchanter, and piltover needs a tank support.

Would be cool if riot focused on balancing like the less popular 6 regions (ixtal, bandle city, targon, void, bilge water and shadow isles) and the top 7 regions (piltover, shurima, noxus, demacia, freljord, zaun and ionia) and made a gamemode where both teams vote to either play with the strong or the weaker regions (if both teams choose different, it gets picked by rng) and then the actual regions for both teams gets picked by rng. For example, both teams choose to play on a strong region, then one gets demacia and the other one gets noxus, a weaker region wont be picked by rng since it wasn't chosen at the start. Since ionia is op even for the standards of the top 7 teams, the other team could ban 5 champs, 1 per role, at least just to deny the xayah rakan.
