It will be modmod but I strongly recomend to use it.
For my play experience and testing different saves in bug thread there is problem with overproduction of units. AI build tons and tons of units and stack them (stacks with more then 100 or even 200 units are common). I know that final solution of this problem should be by fixing AI but for now its not possible to do (lack of knowledge and skills in our team).
Plus from player perspective tons of units its useless micromanagment. Also more units = longer turn times and chances for MAF.
Generaly I would like to see less units but more powerful then now. And maybe cities defense bonus should be trimmed down too.
