I think that all draft settings need increased bans, and not just Dominion.
SR is experiencing the same thing Dominion did awhile back.
You just see the exact same 3-6 champs picked/banned over and over and over again, because they are so overwhelming strong that you can't feasibly run anything else with them on the board.
Ez/Jayce/Kog/Sona/Ori/Anivia/Shen. They're so damn common in the World Finals.
SR really needs to increase the ban limit so that we can see the SR pros run a bit more diversity.
* I know Gragas received buffs to his E but they were somewhat reverted; he was still top Mid at the Na regionals though.
* A lot of characters passed through this treatment at different times on the league life, Malphite, Vlad (everyone saying they wouldn't buy legendary Vlad skin cuz Vlad was in a bad state), Anivia, Gragas, Leona, Ezreal, Nunu, Nidalee, Twisted fate, Corki, Every support, Urgot, Remake Evelynn and Mundo, maybe i'm missing more but these are the ones i recall the most.
