Yeah, let's make another abomination with conversion on demand like CAS.
Tons of doctrines have conversion on demand. CAS is OP bullshit because:
- It has the best airstrikes in the game, which are not only powerful but cheap
- It can leverage the early munitions income to spam inf upgrades, mines etc
- The rate of conversion is unbelievably efficient, 50 fuel -> 150 mun, and can't be intercepted or interrupted
Draining manpower is more devastating than draining fuel is, since CAS gives you every tool you need to deal with the cool toys the enemy gets, while you can also build an extremely potent manpower-only army. Industry is garbage because it's easier to have an army without tanks (or with
fewer tanks as it always is in CAS) than it is to have an army without infantry and support weapons. Every single unit and upgrade needs manpower, while only some need fuel.
We can avoid it being "CAS level OP" by adjusting the rate of conversion so that it's not so "incredibly efficient", like CAS is.
