Eh, I'd advise against making the cells any smaller. If a binary either/or situation (I can use a burst, or I can keep shooting) is forced then the "choice" is lost. I personally believe it's better to encourage people to think it's a good idea to drain the cell rather than force a binary choice on them. I can pretty much predict when X2 goes early access, if the cell is any smaller it will be modded to be made larger.
