The legends are for when you go to sleep / leave for a while. Your dark habitats should fill up in about 25-35minutes right. If you did the same with metal and or electric, things would be pretty balanced. As for space, that's what the 5th and 6th islands are for. I know legends aren't THAT fast, it's juts the 350k max storage helps because well, people sleep :)
