Banning because it's too big of a risk to make sure that your allies can handle such and such champion or that you'll handle it when it turns into your problem is the the reason why bans exist.

There's a couple champs I would ban because of that although what I used to do when no one could remember a champ that they disliked was to just put all the problematic champions into a randomizer and pick that way.
