Well it's you custom champ I guess, so it's your call.

But now that I've noticed how Paradigm Shift has no mana cost, I must say that personally it irks me a bit. I'm sure Ekko used to have no mana cost on his ult on release, but as we all know that raised some issues in his gameplay.

It might be a bit too harsh to add 100 mana cost to Paradigm Shift due to its short CD, but idk. Just saying.
