maybe a bit of a crazy idea but how about giving all khmer units +2 hp per age starting from feudal age. so anything from vills, trade carts, archers, monks, boats. i'm not sure if mangonels are still 1 shottable with 49 hp in castle age. given their winrate (36,49%) i think this bonus could get away from last place. also units that yuo can't create yet due to the age u are in get affect. so with that i mean bbc in imp get +6 hp instead of +2 when u get imp. any thoughts about this?
