Being a hard core SMN myself , the only thing I agree in a sense is Bahamut.

As bahamut don't take any damage at all by mobs or raid bosses what they should do is to let it spawn 3 bodies behind SMN and keep it there.

Let's not forget as well that bahamut pops to help in fight is not a constant fighting egi.

But whatever they do , DO NOT reduce the size of it.
