@Numinous J (cool name, btw)

Well, for one, you don't make items for off-picks, it's just not a good thing to do.

Plus an AD focused support item that was any good wouldn't really get built on supports, it'd get built on the ADC... and then become a must-build on ADC because ADC is a fight of "who can get more money faster". That's why Riot avoids that kind of thing. The closest we've ever had is Avarice Blade, which you couldn't build as a first item and gave a stat that was useless on its own (crit), so you'd never really see it... ever, lol.

@Berryeater

if you look veeeeery closely on the kits of the actual supports, you may notice that a good number have utility that scales with AP (Utility meaning Heals, Shields, Slows, Hastes, that kinda thing.), so they aren't just building AP for damage. In addition, Supports tend to have low ratios on their damage so that they can build AP without turning into burst mages with high utility, which is NOT FUN to fight against (even with just one non-scaling utility, Annie is a pain in the arse).

Meanwhile, AD is a quite different stat to deal with, since EVERYONE HAS A 100% AD RATIO. So having a large chunk of AP might not increase the potential damage of a champ that much due to ratios, a large chunk of AD always will.
