Most jobs don't seem to really use mana or have a meaningful interaction with it. I'm wondering if we could replace MP meters with certain gauges (e.g., kenki). It seems that's the more meaningful value. Even a lot of casters aren't really limited by mana. It originally served as a limiting factor for the number of spells a character could cast in the mainline games, but FFXIV isn't like the mainline games, and it feels like we could have better meters.
