wellp, i think Willbach covered anything i was gonna say, hahaha.

though i will point out something in particular that bothers me... having a guaranteed/increased chance crit mechanic in a kit pretty much says "BUILD INFINITY EDGE", which is pretty much an item that's the antithesis to supporting (pure damage, no tankiness or utility whatsoever). Even reducing the power of their crits doesn't make this not happen (OH HI YASUO AND SHACO).

Also, an AA based support would need more than "more damage" for their innate to qualify them as such (again, damage really isn't a support's priority... or, well, SHOULDN'T be). For example: Taric is a support with an AA based passive, and it mainly reduces his cooldowns (a case can also be made for Ashe, who slows on her AAs, and has the Support tag as her secondary).
