A disposable economy race would have an advantage on defense due to the rapid replacement of units, yes, but they'd also be at a disadvantage on offence, since they can't field as many carriers. And we all know, fighting a strategic defense is bad news.

I would also expect everybody's planets to be chock-full of fighters and troops, regardless of their culture. Most of the time, at least... you could always attack early after colonization, or right after a large fleet has restocked and moved out.

It'll all come out in playtesting, though, and I'm expecting to have to change the numbers at least a bit.
