Why can't I upgrade more than one building at a time, or train more than one class of troops? I have 4 of everything, I would think I could at least upgrade two at a time.
yep, it will be awesome to train more than one troop type at a time!
As I know you can upgrade more than one building and knowlege at a time if you have a second crafysmen and prophet (items which you can buy with bank offers)
