I think it would be great if the colored ammo indicator on Kantrael lasgun was actually indicating the actual ammo consuption per magazine.
For example, as a player fires his lasgun and consumes ammo the color indication should go from green to red gradually folowing the rate of consumed ammo per magazine. In this way, during the heat of the fight the player could have a basic idea about the remaining ammo in current magazine by just looking at the color indication on the weapon model, without the need to check the numerical on screen.
Just a minor idea which is actually lore accurate.
