[@Vec] Cimex and Uri populations are going to increase much faster than Human and dragons pops. 

Cimex will probably grow by a good 500%
Uri will probably grow by 400/450%
Humans will likely grow by 300/350%
Dragons will probably grow by 25/30% (not because they don't breed, but because there are already so many and they grow slower anyway. And there's millions of them in the stars anyway, so not like they'll be dying off anytime soon.)

This is all dependent on wars and whatnot, obviously
