I've just finished quite a few games and in every one of them the only time I would max out radioactives is when I was building Quantum Uplinks, so basically next to never. My metal waste at the end of most games is below 5%, but my radioactive waste is usually over 20%, sometimes pushing 40% on small maps. This seems off. I'm pretty sure I'm not doing it wrong since I'm usually beating normal AI's in 1v1 and 4-way FFA. There just doesn't seem to be anything that's really radioactive heavy in the game. Bombers kinda sorta are, but they are also metal heavy, so they're getting throttled by the rest of my economy anyways.

I feel like there should be units that are much more radioactive heavy than metal heavy, relative to the usual spread of resources on a given map. This would add to player choice and force tactical adaptation, rather than just be something that you get punished for if you're extremely short on it.
