The anon do got a point. You should go by what they've currently shown, not how you assume or think it. True she can use DF freely now but what you guys fail to think about is if her feats are like Tartarus. Keep in mind that Etherious was the only reason why she had temporarily obtained DF and made her immensely powerful in Tartarus. But now she can use DF at will, you don't know if her feats are the same or possibly higher and so far she's currently shown, its pretty weaker. I wouldn't say the CSK is Lucy's power unless she summons him again if there's a different way, but Aquarius noted that she is capable of handling to summon him and since by needing opening 3 gates at once (which takes a lot of magic which is known to be a forbidden technique) to use the Recompense Summoning and him being the most powerful celestial spirit really shows how powerful Lucy is. And lets not forget Star Dress which it can not only make her fight now alongside her spirits, but increases her own power which makes her more stronger and so far, Taurus and Sagittarius forms were the only ones she's shown a bit of extent to them than the others and together with her spirits, they can combine their powers which of course would be strong. Anyways, both of them never shown the true extent to their improvement but going by what they've currently shown, I say Lucy got this.
