If someone on your team says they have trouble playing against a specific champ
You're way better off banning that champ than something else entirely because it's "meta OP".
Like, if you're in bronze and your ADC says they have trouble with dodging Blitz grabs fucking ban Blitz over something like Zed or Vayne who are only objectively strong if played w/ a high amount of skill (ie: not in bronze). On which note don't yell at your first pick for banning out a champion they have trouble with even if it's not "OP" (I admit it's selfish to put all three bans towards your own lane, but if they use one like that then who cares. It's so THEY don't feed, which is a good thing)
(Note I'm talking about ranked here, it's probably better to encourage people to lrn how to beat their nightmare champs in normals)
