AD Carry Junglers and Their Struggle in the Current Meta

I feel that for the most part AD Carry style junglers that can not utilize rageblade or sated devourer are not as gold efficient as others, causing them to be irrelevant in the meta. My evidence? Where is Kha'Zix?

Kha is bordeline trash tier in this meta, why? He has no utility, his kit entirely revolves around kills. Without killing, Kha is essentially useless. Because of this, Kha needs to build AD, he is very dependent off of his AD. What are the costs of his items? Hydra, 3500 gold, Black Cleaver, 3500 gold, Youmoos, 3200, Duskblade, 3250, Maw, 3250, Scemitar, 3700, Deaths Dance, 3500. Granted you wouldn't build all of these items on Kha, but for the most part people would really consider these items.

However, look at champions that utilize items like rageblade, it's considerably cheaper, provides two types of damage for tanks to have to build against and works extremely well for clearing, and fighting extensively. Champions that can utilize the attack speed, magic damage on hit items are dominating the carry style of jungle play, and for good reason. The items are cost efficient enough for a jungler to get. Junglers get considerably less gold than laners MOST of the time, simply due to the fact they no endless waves of minions to kill. Because of this, they need to be extremely gold efficient, the reason for the cinderhulk junglers becoming extremely popular and meta was due to this same very fact. The item provided a great deal of stats and utility for the cost, making it a go to item for junglers, one of the lower income roles. You may be able to argue the same for the warrior enchantment, but can you think of an item that compliments it the way guinsoos rageblade compliments devourer when sated?

I have not really thought of a solution to said problem, but I feel champions that lack the utility and need the AD in the jungle need a little love, maybe an item that's more gold efficient and compliments warriors enchantment? It would spice up the jungle scene I feel. There would be more diversity in carry style junglers. Anyways, thanks for taking the time to read my post. Please do leave your suggestions and thoughts in the comments, I'd love to hear what you guys think about the current meta!
