how to make team builder actually good

bans/ not blind pick. bam how hard is that riot? Id rather not go into a game mode where %%%% bags can pick broken cancer champs like soraka because they cant win in ranked because people ban it. That and playing against the same champion is just a shit fest so if you get lucky and they actually pick realistic champs you dont have to have a dumb game where 2 shens. Other than that team builder is a cool idea just needs some very needed tweaking.
