User blog comment:TNickxx/Y U NO AD Support/@comment-1330314-20161207203539

I used to be against the idea of an AD support, as I thought AD itemization would never be conducive to supporting, by dint of being expensive and inevitably bleeding into damage. Now, I realize AP also pretty much always has a damage component on AP supports, yet is still an attractive stat to them, and mage supports are also legitimate. I'd love to see AD supports properly implemented in the game, and it would be interesting to see DPS held as an important contribution alongside CC or utility. In fact, a few current marksmen, e.g. or, could easily turn into proper AD supports, as would champions like Lee Sin, as you mentioned.

The kit you're proposing looks a bit like a more support-y Xin Zhao, which is interesting. I may have some criticism for the details of the implementation, but overall your champion does have enough utility to qualify as a support, and could definitely bring something completely new to the game. One thing to bear in mind, though, is that currently full AD/crit itemization inevitably turns champions into carries, whereas supports are expected to thrive on low gold income: you need to make sure that, in the current environment, your champion can do well without too many items (which sounds likely, considering the percent health damage), but also doesn't just turn into another Yasuo if he gets fed.
