Perhaps it is too late for .80, but I would love to see the unit upgrade system improved and expanded.
I would like to be able to upgrade individual units to the latest weapons and armor, at a reasonable cost.
I would also like to be able to combine smaller units into larger ones, for example 2 parties = 1 group, 2 groups = 1 company, etc.
As it stands now, we have to discard well experienced troops as technology progesses.
