Kindred, Feast and Famine Incarnate?

Personally I was super excited by the whole idea of a ranged jungler, especially as that would allow for other ranged junglers. But Kindred has a huge problem with his/her kit: It's extremely feast or famine because of the passive and low ratios. Low ratios means don't build damage, instead build on hit, but Kindred does too well with on hit and now Riot wants to destroy all other sated ranged junglers. Kayle and Vayne emerge from the jungle after 20+ mins like Master Yi, fed, but with nice counterplay: easy to invade and easy to pressure lanes. Teemo and Twitch both provide good assassination and mind game potential, at the cost of slow clear speeds and easy camp poaching. Twisted Fate loses access to an entire spell, wave clear and functions like Warwick post 6. I do not see the need to nerf all of these champions and more just because Kindred has poor interaction with sated. Current design can make a Kindred have 6 stacks by poaching, and 4 stacks from kills, with a BoRK by midgame. This gives Kindred 8+12.5(lamb)+12.5*.4(wolf) =25.5% current health on hit. You can see how that is super abusive with live sated. If Kindred had better ad ratios (from lower full ad to higher bonus ad) the on hit could be nerfed. Then lane Kindred might stand to lose the heal or make it weaker/ champions only. Then Kindred wouldn't be as dependent upon getting stacks, sated ranged junglers would still be a thing, and lane Kindred wouldn't be abusive.

TL;DR Kindred needs stacks to do damage, which edges out other sated ranged junglers and minimizes his/her ability to build ad.
