I don't understand the reasoning behind giving him a new energy system. It doesn't promote anything different from what mana. In fact, it's just the exact same thing as mana but he just gets the added benefit of getting more back with more attacks or kills. What's the need to give him a new system?

You might as just made his passive, "He gains 20 mana on each auto-attack and 40 mana on a kill." It would be the exact same thing.
