The current system of fleet upkeep seems to flawed.  Once you buy the supply limit increase, your upkeep will always be at a set rate regardless of how much supply you are actually using.  This does not make tons of sense, and makes the later supply limit increases a penalty more than a bonus.  Those 'upgrades' aren't free, you're paying a fair chunk of resources to increase your supply limit.  Personally I think it should be handled like Warcraft 3 did it.  If my current supply usage is below the base limit, I should have 0% upkeep.  If I go 1 above that threshold, my upkeep goes up.  This will continue to change as my supply goes above and below the different threshold levels.  This way if I'm at a high supply level and my fleet gets wiped out, that first ship I rebuild will not be getting taxed at 50% or whatever fixed amount level you're at dictates.  Thoughts on changing this?
