Why should you take elite inf units?
Artillery gets value on them fast and they can be attacked in the back because you don't have enough money left to protect it.
Just an example: is it better to have 2 Har Ganeth executioners that can fight at two places at the same time or 3 Witchelves that can fight at 3 places? Same price btw.
I have no idea how to change that but it has to be changed! Maybe a MA Debuff if units fight units that cost more
