Change an item instead of nerfing it (a proposal for face of the mountain becoming a jungler item)

TL;DR : Make FOTM into jungle oriented item. Skip to bottom for Build suggestion and new passive.

So as most of you know, riots attempt to better the jungle has backfired and it's actually incredibly difficult for most junglers to do their job. Aside from the few strong AD champions that have little problem clearing a camp, most other junglers suffer with long clearing and punishment from the fact that these camps friggin' hurt now! The new items leave much to be desired and there's even been math done to show that a duo lane both bot and top will produce more gold than a solo lane with a jungler... for that reason I want to propose a change to an item that obviously requires a nerf. The relic shield and it's build path if not for the team passive, would be an ideal jungle item.

I want to instead of nerf the item, shift it's purpose for a jungler. give the execute ability a nerf when by yourself in the jungle, and the full capabilities while taxing a lane. It would provide a bit of help to whichever lane the jungler chooses to gank, along with some sustain for himself. Change the build path as well..

Relic Shield Price: 335g 50 health, 5 health regen. Unique passive: basic attacks execute neutral monsters below 90 and heals you for 1% of your maximum health (minions executed this way will retain the old relic shields passive [200 hp execute and heal ally for 2% instead and grant them the bounty]) recharges every 30 seconds (max 3 charges because of the fact that you will be farming your neutral camps more than the lane at times)

Build path : Hunters machete (300g), Rejuvenation Bead (180g)..

Of course this would mean making other jungle items more cost efficient to avoid this being the only item to be used for jungling and what do I know about balancing the meta.
