Why does Riot recommend Riven in the jungle?

Recommended items on Riven seem to suggest she works best as a jungler, but after riot attempting to nerf her laning and the current jungle being so massively OP, she she can barely do a single clear, and i'm talking just the first 3 camps here, and that was with a good leash.

Even by lv 11, JUST taking raptors destroyed about 1/3 of her health, and the shield is practically useless. Because it now only last about 1.5 seconds, even if you time it perfectly to start just as you take an attack from a large monster, it won't be up by the next attack, so the shield blocks just one attack every 10 seconds. Through out the game, she constantly struggled with clearing the jungle, and with out the reliable high farm from lane, she is very under powered and there for has terrible ganks too, because she can't afford enough items.

So it's a viscous circle; too weak to farm jungle --> no money --> no items --> can't gank --> no money etc

I'm not saying we should buff riven, because she still seems to be able to go ridiculously OP in lane with a kill or two, but why can't they find a middle ground? If riot recommends jungle items, then they clearly think she should be a jungle, well not in the current state she isn't . But if they could work her it to more of an actually fighter, rather than a bull shit AOE assassin, it might work better.

Personally, I like to try lots of different champions. I do well as champions like Rek'sai, Vi and Shyvana, but every time I try and play a new off meta champion, I lose and lose hard. So I guess should could take all this to be another 'there is zero jungle diversity' thread, but even champs that are OP, that riot actually recommends you play in the jungle are actually so weak it's ridiculous.
