What the problem is: Meters like Focus , Momentum , Resonance etc.. etc.. are not clear from the start.
Why does it matter?: Many players will not discover that bar for along time, and it is also a bit hard to check while fighing, I would suggest to make it more "Visible" and "Clear from the start"
How does it affects your gameplay?: I admit that it is my fault that it took me 10h to find that bar, but I would love something more clear.
