correct me if I'm wrong, but didn't revives used to take 10 energy? so effectively for the same cost you get half as much revives now, which is stupid, considering how much ce costs now, and how much you have to grind to get 200 energy. (about 23200 crowns) if the cost of sparks were reduced to 100 ce per 10x then it wouldn't be so HARD to get sparks, I'm currently saving for elite orbs so 100 energy would be a lot more reasonable.
