I still don't get how Legions are supposed to be better than Levies.
Sure, Legions don't take pops away from your jobs and your research, but they cost a lot, cannot pillage cities (and pillaging cities makes MAD dosh), aren't any bigger than Levies because they take troops from the very same region, and they're not any stronger either because Levies receive the same technology buffs.
I don't fucking get it. Why not stick with Levies for the entire game?
