Fairy Tail Thread (Spoilers)

Ok maybe useless was the wrong word, what I am trying to get at is that after the CSK disappears, she will end up weaker than she was, unless we expect her to blow up a gold key everytime there's problem. Summoning 3 spirits proved to be no improvement (They tried to hold the demons away and were taken down in a couple moves) and I'd have liked better to see a new technique using 3 spirits at once which'd make her stronger than for her to lose the strongest one she has which makes her weaker.
