The rule for FMC is 3 cubes, and personally that seems like a good number to me. I'm just wondering though: is there anything you could do with 4 cubes that you couldn't with 3? What about 5? Would there be a use for having 10 cubes for FMC? At some point having more cubes is just going to get confusing. This is of course a strictly academic discussion, I don't think the rule will change, and I am in no way convinced that it ought to.
