Given that during the global 2 second cooldown he will replenish 20 energy, I don't think he needs energy-refund in his abilities. He already has a forced downtime. While it irked me not to give him an energy-refund (which all other energy champions have), I felt it was for the best. It's also why on my thread I made his costs 60, instead of 50 (which was my first choice). In your idea his abilities essentially cost 30 energy, and the point of energy is that you can become "exhausted" so to speak - which wouldn't happen with costs that low.
