Actually, when i saw an old movie about the old gameplay, i saw that you had a chargee bar to show how much you've charged your attack. Actually, i think it's kinda cool, as it not only give you more control about the charge attacks, but also let's you do sme things regarding it, like a status that double the charge bar, the equips could shorten the bar, instead of speeding up it increase, and it could easilly fit around the heat "bar" (don't know what to call it, as it isn't a abr for itself...maybe heat core).
