Moving each tech level of troops down a barracks is so simple and elegant; love it. I do wonder what to do with the last level of barracks; it will become useless.
Easy solution plus 1 experience to all troops it can train.


What I did was give stonewalls a happiness bonus.

15 for stone, 25 for large and 30 plus 10 law for epic.

For me this is justified, whenever I take over a city with 20,000 plus inhabitants they get exterminated thus reduceing the population enough that all the happiness buildings make it unable to rebel and this is excluding the stonewall happiness. This in turn helps the A.I. and in reality those stonewalls were not garrisoned heavily.

And if were living back in those times would you be happier behind a rinkydink palisise or an epic stonewall.
