New Bond of Stone in PBE on tank Junglers

So a lot of people see bond of stone as the support go to keystone and I am pretty sure it is going to stay that way, but one thing I want to point out is how good this might be for some of the tank junglers that do not have a keystone currently. When I saw this keystone the first 2 junglers that came to mind were nunu and olaf, idk if olaf benefits from grasp but I do not think it would help him very much. The new bond of stone reverts the nerf to nunus new q passive and when ganking a lane he will be able to spam e and the laner can get a lot of healing since he is getting 15% max hp extra from the keystone and his passive. Olaf as well can benefit from the health and it will let laners heal for a lot since he also stacks alot of health and his q is very spammable. I am not sure about jungler that take colossus but I am thinking this keystone will bring back tanks back that did not have a keystone.

Thoughts?
