Actually, presumably that you're referring to the Bezel Gauge (the red things at the bottom of the screen that power your super attacks and shatter when you get too high on scratch damage) there are a couple of ways to help out with regenerating it. Charge up your handgun attacks high enough (or use Smash Grenades) and you might "Break" an enemy's gauge into sections, which will give you a Bezel back every time you get to one of the break points on the meter, not just when you empty it entirely. I actually really enjoyed the resource management game, calculating hero actions vs. anticipated Bezel return on successful attacks. Also, two characters with machine guns (only possible later in the game) and one handgunner or grenadier mopping up afterward is quite effective (particularly if one of the MG'ers is Vashyron, who gets Full Scratch earlier than the others).
Resonance of Fate is one of my favorite RPG's of the current generation. I love the steampunk-y aesthetic, the combat system, and (of all things) the ability to change character wardrobes. I can see why people wouldn't like it (I hated it for the first five hours or so, until things started to click) and it's not perfect by any stretch, but it's a solid, unique game and I think it deserves a shot if anything about it sounds appealing.
