I would love to hear the devs' reasoning behind these ridiculous times, from a gameplay sense. From a business sense they obviously want us getting frustrated and coughing up 40+ crowns for retraining. All while they keep adding more and more defensively to boot.
Funny thing about frustration though, it's just as easy to put the game down and not play it for a few days by the time planes go from novelty to necessity. In fact that notion really synergizes with those two week build times.
I don't understand how this company doesn't have one person in-house who's played past enlightenment age without using a developer build. If they're not dealing with tanks, planes, silos, war matchmaking, sandbagging and the lion's share of the oil game then they're completely out of touch with the majority of the player base at this point.
