Again, I can't seem to leave a comment without it devolving into a math nerd fight I can't even follow.
Anyways, on the topic of more roles for leaders I fully support it but I don't think it will come with this update. What I do hope will come, and what I assume would just require a minor tweak to a variable or two, is making Ground Officers spawn much more rapidly. I personally think they should be more plentiful than Naval officers since I'd bet recruiting standards would be low (no offense to anyone in the Army but an Naval officer is probably a literal rocket scientist at least). However, I'd settle for them spawning at the same rate as Naval officers for now.
What would be even better is a way to tweak leader spawn rates from the game options menu, just like you can with survey speeds and such.
Also, making Scientists lead survey ground units instead of ground leaders would be really cool.
