check my question about the tree of enlightenment in the German forum, the troop production was calculated there when all optionals have been researched and calculate the harvest times 4-5 if you can harvest like that. The result isn't bad.@Jammin I checked my troop production of a lvl 35 wonder and I am not excited from it, but maybe that changes with the higher chapters? If I could give back some of my expansions, than I might be interested in this effective ork production. Maybe I build it lvl 1 or something, gonna see.^^
Currently the harvest of all troop producing wonders is bad because a lot of research is not finished + optional troop upgrades.
