Dragons of Atlantis - Is it better to upgrade garrisons or build more?

In Dragons of Atlantis it is far better to build more garrisons than to upgrade current garrisons if you are looking to lower the amount of training time.  Upgrade one garrison as needed to be able to train whatever troop you are working on but after that it is far more efficient to build a new garrisons.  As an example.  If you try to train 1000 conscripts with a single level one garrison it will take something like 7 and half hours.  Upgrading to a level 5 garrison will only reduce the time down to somewhere around 7 hour and 15 minutes.  But building a second garrison will reduce the time down to around 3 hours.  That is an incredible difference.

I recommend you make about 15 garrisons depending on your play style.  You can make up to 19 if you know what you are doing.  Dragons of Atlantis Heirs of the Dragon is all about managing your buildings to have the most efficient troop training times while still having enough population to train troops.
