New change to GU templates looks interesting. For people who don't like researching individual units and especially the HQ units this is probably perfect.
One change I might request is that in this step:
If the racial armour modifier or weapon modifier has been changed since the creation of any class in the original template, a new Ground Unit Class will be generated for the matching element in the new template, based on an upgrade of the original class.
could we have the game first check if a class with the current racial armor and weapon modifier exists in the current unit series, and if so use that instead? This would apply even if the latest unit in the series is not just the same design with better stats, meaning that if I want to upgrade my formation from VEH-based tank to HVH-based tanks it is as simple as one button click. Overall this would make the system flexible for different playstyles.
This would allow people who prefer to have the R&D cost of developing their ground units to still benefit from the Copy+Update function, while the default remains the described behavior as I think most will prefer it. Alternatively, a pop-up window with a checkbox to select between these behaviors would be nice, but as this requires adding GUI elements I would not ask for that much extra work.
