It seems strange to me that the experience a unit has earned is simply generic XP
and that when it reaches a threshold, you can choose from among any available promotions. Even in the field.
Even if your unit has done nothing of the sort.
Your Scout hikes over flat bare land and discovers some villagers, wonders and a continent?
Congratulations! You're now better at moving over hills!
Wait, what?!?
I would prefer the promotions to be tied more closely to the things the unit has actually done.
E.g. If your Scout moves through say 20 Woods, it should earn the promotion to move faster through Woods.
If your Warrior gets attacked by ranged units often enough, it should get the promotion for defense vs Ranged attacks.
Perhaps some abilities should only be earned by training at a suitable Encampment.
e.g. Train at an Encampment with a Barracks next to a Cliff and get the promotion for scaling cliff walls
On a similar note, it seems to me that moving units through Woods and Jungle should form footpaths, or more.
If a Scout hikes back and forth through the same Woods tile, don't you think it would know its way and be able to get through faster?
If a Warrior (which is really what, 20-100 men?) tromps through woods, shouldn't they leave a path?
Maybe a path though Rainforest should become overgrown if more units don't follow within X turns.
Maybe these paths should be formed between the side of the hex the unit enters and the side it exits, rather than forming a generic path allowing any travel through the tile.
Maybe units on "home" territory should be able to move faster than enemy units of the same type.
Maybe a Tank unit should have more trouble moving through Woods than Knights, at least until someone builds them a road.
