@Riot Energy resource - runes, existing champions, and the future.

After seeing some footage and looking at the current numbers of Shen's update, I noticed that his total energy reserve and energy costs have increased comparative to his current state.

My questions are: Is this a test implementation similar to the ammo system that was used on Graves(for Jihn)? If so, will you be using this on future energy user updates or perhaps an update to energy itself? and Is this a step toward making the balancing of the energy system easier?

Other thoughts: Will runes be affected by changes to energy, because the scale at which they were originally balanced was with the 200 limit in mind. Will the runes be removed or updated? With the increase, will you add energy regen to items/masteries?
