Can we make a Mana equivalent for non-magical champions?
Okay so the title is a little confusing, so let me explain.
Mana is portrayed as a fuel for magical abilities, at least in most fantasy games. Essentially, a character will spend Mana to magically empower an attack, such as casting a ball of electricity or creating an illusion. The ability to use magic is gated by how much Mana a character has available to them in the same way that keeping a fire going is gated by how much fuel you have available for it.
However, Mana doesn't gate physical activity. That's why most characters in MMOs and RPGs have an extra Stamina bar, since non-magical characters don't need Mana to do perform their feats.
So why does it cost Mana for Darius to swing his axe in a circle? Or for Caitlyn to fire a net out of her rifle? These aren't magical activities, and some characters do the same things WITHOUT Mana gates, so why do this?
Maybe on characters like Darius or Fiora, you could introduce a Stamina bar. It would be essentially equivalent to Mana in every aspect, just with a different name and a different color (like Black or Purple).
This definitely doesn't need to happen at all, but it would be a nice little edition.
