Since in late game national troops become very very useless (ghost rider, 5 death gems, tartarian gate, 10 death gems, bane/wraith lord 10/40 death gems, and similar summons that vanquish them all) I've some proposes to do:

I have an idea. Let's look at what all of the summons you have pointed out have in common: death magic!

Let's talk about the early summons that people use that are really good: Banes, Wrights. The later on Bane Lords, Wraith Lords and then the summons that you list.

The only other path which comes close is Blood ( demons are simply *really* inexpensive compared to what you get ).

Were it not for those two paths national troops would be effective for far longer. Sure national troops would be dominated by mages in the end, but isn't that what we expect?
