I actually like the fact that many summons are (in theory) open to all nations, and it's their mages/gem income which decide what they get.

So you are saying everyone in the universe has the exact same technology at all times no matter WHAT? That's what national summons are, the natural imbalance of technology, or in this case magical knowledge.
