Hero power calculation – why does a 5* Hero with lower stats than a 4* Hero have a higher Card Power?

Thanks. Then I would blame the dev. The base power from hero rarity is an illusion that has no real intrinsic value to the rarity but rather an arbitrary number. The illusion gets worse for older 5* because their skills aren’t as good as new ones. This the power calculation is just a fake to make players feel good about all 5* while in reality it is for those who have newer heroes only.
