The "units trading" systems is a double-edge knife IMO. On one hand, like you said above, but on the other hand it could bring up a kinda black market for units. Player could and will just out right buy the unit that they want instead of summoning and that make the game lose a lot of money. I think with how Alim/Gumi makes money which is mostly through summoning this would create a lot of problems for the developers.

This is a great idea but there is a pretty big flaw, in this idea.
