Having taken a break from the game for some time, it was nice to come back to see that all your units do not just automatically upgrade when you research a higher level on the research tree, and that you have to use resources and spend time to upgrade a Level 1 battleship to Level 2. However, I do find that I am using up a lot of resources to upgrade.
So the question is, which is the better use of your resources, to build a completely new unit, or upgrade all your existing ones?
Say you have a stack of 4 Destroyers, and you want to upgrade them from Level 1 to Level 2. You could probably use those resources to build an entirely new unit, and have 4 level 1 Destroyers and one new Level 2 one, instead of four Level 2 Destroyers.
What do the old veterans on this forum think? Which do you guys do?
