between adc and support, while this is kind of a lame question since they all have heavy impacts.
Both adcs and support tend to have one or two seperate options that can do similar things for the lane. However it isn't to say that banning a champ in these classes is stupid. Once again, all roles have powerful champs that can be worth banning.
I rarely see ADC's banned because chances are if you're good with one, they'll be another one you can play with the same playstyle at the same level.
With Malphite, Amumu, Blitzcrank, and Shen constantly being banned out, that means that Top, Support, and Jungle already have bans and I've seen more mid bans than ADC bans, even though I haven't seen them nearly as much as other Top bans. --- Generation 30: The first time you see this, copy it into your own signature (on any forum) and add one to the generation number. Social experiment.
All ADCs boil down to how strong their right click is in the end. There's no game breaking utility like Amumu's ult or Blitzcrank's grab or Morgana's trololol Zhonya. --- A game that promotes slavery and gambling under the illusion of 'friendship' and 'sportsmanship' is automatically an awesome game. - dydt
Banning Blitzcrank is a good idea, Alistar isn't a horrible idea, the rest are useless. Banning any ADC is a huge waste. PLENTY of mid and top to ban out, certain mid/tops like to go Jungle. Many months ago banning Lee Sin and Rammus was a thing. --- #1 LoL Poster NA: http://www.gamefaqs.com/boards/954437-league-of-legends/63627116
