This needs to be looked at because it looks like bad math unless it was intentional that orc production per square be drastically downgraded. So at the end of Alumi you get level 31 and you can produce 740 orcs in 12 hours in a 3x7 armory, so orc/square production is 740/21 = 35.24. At the end of constructs you get level 33 and you can produce 870 orcs in 12 hours in a 4 x7 armory, so orc/square production is 870/28 = 31.07, for an approximately 12% decline in orc production. Population required per square for level 31 is 2430 for 21 squares or 2430/21 = 115.7 population/square. Population required per square for level 33 is 3973/141.9, or an increase of population per square of 22.6%. For orc production to keep up with the increased population requirement take 740 x 1.226 (for the increased population) x 1.3333 (for the increased size) = 1209.6, or 1210 orcs/12 hours. Combining the increased use of population and increased number of squares we have an effective 39% (1210/870 -1)*100 decline in orc production. If this is not an error, it is very frustrating that we need to apply math to appreciate doing what one would expect to do in the game, upgrade buildings, is a very bad idea. I've just upgraded everything on live, but if this is intentional, I will be rebuilding them one at a time and leaving them at level 31 because it is simply a bad game play to fully upgrade armories with this kind of drastic downgrade in production/population.
