bans doesn't work, when URF originally ot released about 3 days after it got released everyone was picking the same 10 champions every game, after much complaining riot disabled about 20 champions in URF, the strongest champions URF had, you now saw the next 10 strongest champions every URF match, this is because people love spamming OP champions regardless of how fun they are.
I often see people say ''that's not true they just like playing them!''
2 very OP champions in original URF were urgot and evelyn, champions which in SR you maybe saw once every 1000 games yet they were seen every game of URF, that's because, like I said, all peopel care about is picking OP champions.
