Specifically look at the box to the right, what it promotes from and into varies each game. 
So this is bound to cause a lot of confusion, we should probably pick a game (9 or 10 due to Laguz I'd suggest) as a base to get our classes off of.
If you want a class not from those fire emblems we could find a way to work it into another promotion tree.

Thoughts?
