[Suggestion] Level up Abilities
llow units to gain abilities as they level up rather than just have all special abilities from the start and only gain stats as they level up which seems to be what the current XML allow.
This would be a far better way to let units gain in power as they level up without making them too powerful at first.
Oh and I agree the game should tell you what effect a unit levelling up has, currently for most units its just health although you can make a creature that gains stats but not abilities at certain levels.
