In Civ V, there was a mod called "Promotion Expansion" which allowed you to level up a single unit to past level 20 without running out of promotions to choose. I would like to see something for that added to Civ VI if someone understands it well enough to do so. Also, while it's being redone anyway, perhaps adding a +1 combat strength per level to it as a base (so a lvl 7 warrior would have +6 to his base attack power, in addition to the promotion benefits). Anyone up for that? Thanks!
