the only AD champs i can think of who could go into botlane could be served just as well building the Ancient Coin or Targon Brace lines.

unless your utility scales with it, building offensive stats on a support kinda just makes you easier to kill, since supports get their power from said utility.

plus, building offensive stats make it easier to accidentally killsteal, which isn't really a thing you want to do ever as a support, since your ADC needs the money way more than you do 99.9999999% of the time.
