I've read both Planned features updates, but couldn't find anything that talked specifically about building times or construction queue in infrastructure. To be honest I can't believe it takes more than 30 minutes to get lvl 2 on Weapons armory (Yes, I just started playing) I think time should be reduced at least a little. I played back in the day Space4k, Ogame and Vendetta1923 english servers and I don't recall buildings taking this long to update from lvl 1 to lvl 2. I know that getting your Boss Office upgraded reduces time, but for new gamers, "Newbies" this doesn't help. It would be nice to see for example.
Weapons armory
Lvl 1: 2 mins
Lvl 2: 5 mins
Lvl 3: 10 mins
Lvl 4: 15 mins
Lvl 5: 20 mins
Lvl 6: 25 mins
Lvl 7: 30 mins
Lvl 8: 45 mins
Lvl 9: 1 hour
Lvl 10: 1 hour 15 mins
this would help on getting a nice quick start and not discourage new players with long queue for buildings.
