Sphere Grid is one of the best building systems to follow my purpose of assigning classes to characters! It makes you skip nodes or use them for different stats!

I like it the way it is! Much much much better than XIII Crystarium that is dumb fix and you can skip just a few nodes! With Sphere Grid I can really customize following the classes idea and having some RPG expertize I won't of course make the mistake of unbalancing characters beyond needed! Lulu is a Black Mage and has to be with low Defense but it doesn't mean I won't rise her Defense at all!
