I still have 2 Kais left in the Shop because I bought all the stamina available, and I don't regret it one bit. Now my max STA is close to 200, and all that stamina is really useful for grinding events, especially World Tournaments.

I never use stones to refill it, either. I'd rather spend 1 stone to buy 5 character slots.
