Since so many single target junglers are kill based (Tryndamere, Shaco, AD Sion) maybe you could tweak the passive again slightly to grant the same bonus on champion kills, and maybe even assists. While they don't typically build on hit, these champs would be able to take advantage of on hit pretty well.
