White Smite Reform

So, I've been thinking about the smites introduced in season 5, all three of them...wait, you're telling me there were four smites?!?! O.o After looking at it, white smite just feels like it gives too little reward for so much risk and can mainly pan out, solely in solo que games where the jungler that builds smite is super lucky. A small gold buff (which would require you living in the opponents jungle to benefit from it) A movement speed boost (which can be useful, at times) WOOHOO! so much fun! so much advantage! many fun! much wow!

I've been contemplating different changes that could make the smite more viable.

How's about developing a charge system for wards? Similar to how Sightstone regens wards whenever you back to base, allow white smite to build a charge whenever you kill an enemy camp (maximum of 2 charges storable) and allow the jungler to expend charges to place green wards. Junglers like: Nunu Reksai who typically enjoy building sightstone for the vision advantage could use white smite and save the item slot or gold for something more gold-efficient. The ability to be granted wards for stomping through the enemy's jungle and taking camps allows more vision at the expense of safety (which warding helps with)

A couple more tweaks with numbers and possibly maintaining a little bit of the movement speed boost could prove to bring White smite out of the dark and into a more viable light.
