The only tankable ADCs right now are Graves and Quinn (And both Gnar and Urgot, if you somehow want to consider them), and currently any utility ADC is considered supportative, being Ashe and Kalista, but none of these champions (except the two within parentheses) can play purely as Tanks or Supports.

We have ADCs that can be played as Mages, Fighters, Assassins and purely Marksman, but making one being playable as Tanks or Supports, although attarctive, can marvelously fail.
