The main con against bans in ARAM was how it "ruins the all random factor", therefore they removed it. Now, when I start a game I see this: everyone rerolls like crazy until gets a favorable champion with heavy poke damage or if the rerolls were unfortunate they pick someone from the ditched champions' pool. It effectively means a player can choose from 8-10 champions in every game.
Please explain me Riot or any of those who were so against bans: this is not against your precious all random factor? I cannot even see the "all random" at all.
How did bans make ARAM less random than these things do?
