Thinking about it, maybe it's too late for them to have a major role now. That's why I wanted them to show up right in the start of the arc, that way I woudn't have the feeling that this is only FT's fight (even though this is a manga called Fairy Tail). Maybe destroying the remaining Faces would be good but not satisfying enough.
