Instead of using "actors" for summons via Monsters, I think summonable monsters should be enemies. This may function as maybe a quick add on or something, but I'll be able to do a lot (with a certain game I decided to start--which puts Blizzard's summons to THE MOST use.)
But...creating actors T_T And you see, I have to create the enemy version of them, so that you battle them first THAN they join your team, etc.
But... eh.. Using Enemies for monsters, and Actors for pets makes more sense.
