Imagine the struggle...
https://i.imgur.com/oGATAaA.png If this thing happened to me as of today, i'll either have to wait a whole day or rush like crazy to level up to get that one tiny blue essence for buying a 6300 champ that I'd really want. I imagine the struggle the new players must go through today to buy the expensive champs who looks interesting to them. Like, they either want to get really really lucky in the level-up boxes or keep themselves from buying any other cheaper champions just to have this occasion. And now, if this happens, they'll have to either wait or rush to get what they want, their excitation of buying THE champion they wanted quickly murdered by this crappy system. This is not fun at all, this system is a direct downgrade, a frustrating concept and, most of all, less rewarding than before, like it has been proved several times by other players
