Bond of stone mastery

Now i just wanna say bond of stone (keystone mastery in the resolve tree) seems to be unwanted or unneeded. I would say sure this is the preseasons but since the other two, a heal every 4 seconds or so and a decent shield as well as the new item knights vow which does a heal effect, i see no use in Bond. In my opinion i believe it deserves a new mechanic or buff, now I would say adding a heal from a % from surrounding allies´ damage would be nice, but a nerf to a certain part of it might be needed to say balance it out.

Example 1: Add 1% heal from all surrounding allies Add an additional 1% taken from allied champion damage to you

Example 2: Add 1% from all surrounding allied champions Subtract 1% damage reduction

Example 3: Add 3% heal from allies(with a 5 sec cooldown) nothing else

If you think that its good where it is and have a different idea of where Bond of Stone is, Please tell
