Spirit of the Ancient Golem: Jungle Item, or Best Gank Item?

All of the Jungle Items as of late have undergone certain changes to increase gold income. We've seen reworks to , a formerly neglected item that is now seeing much more use. We also saw a nerf on the 's damage, which, if you are building attack speed, wasn't that big of a deal.

However, I want to know the reasoning behind the Conservation Buff on which was probably the best item for a wandering Gank Jungler.

Why is it the best? Because it has the Tenacity Passive, reducing (almost) all crowd control effects duration by 35%. Only two other items in the game have this buff, but buying the Spirit of the Ancient Golem allows for Ninja Tabi boots (Most of the reason to buy Mercury Treads is the Tenacity buff), which reduce creep damage taken and make an already effective Jungler even more effective.

However, instead of the Bounty Hunter bonus, which is far more preferable to a ganking jungler, it gives the Conservation buff, which requires constant jungling to make full use of it's effects, allowing pauses only when it's passive is not stacked at 40.

Riot, I'd like to know, why is the best item for jungle gankers given the worst passive effect for a ganker?
