Keystone for jungle(rs)?

So,

i was playing as jungler in the last week quite often and i thought about my Runepages. As a jungler i would really like to see a keystone targeted for junglers specifically. Playing a champ on predator for example is good for champs who have good pressure on the map like Hecarim but i don't really want to play other champs who also jungle well with the same keystone mastery. Besides the smite jungle item i feel like there is a lack of interaction between my role as a jungler and the opposing team and my own team. Most of the time i try to get a gank early, so that i can help my lanes do well but i feel often left out because all the action already happens on other lanes.

Perhaps this is something for all junglers, because i haven't seen much variations of Runepages on enemy junglers mostly stuff like electrocute which is still fine, but in the first 5 minutes of a game it is really awkward that nothing really happens when you farm your jungle. My guess is design a jungling runepage that gives you 3 main keystone choices like the others, or is that already too much idk. [sg-zephyr]

Since there will only be purple smite in the future maybe that adds some diversity into this role again.

I play on Eu West btw
