I mean, the energy runes are pretty dismal (+50 max energy if you really try, or maybe increase your energy regen by a whopping 15%), and especially since there are only 3 (albeit very good) energy champions, I would assume that you plan on releasing more?

It's a cool system, it would be a waste just to have 3 champions use it.

I wouldn't mind, I love most of them.

How about one that's not from Ionia? Not that I don't like them, but we could do with more Void / Shurima Desert etc
