I'm not so sure about Lucy being on par with Juvia when she's going all out (like against Meredy "Who did you say you want to kill?"), but otherwise I couldn't agree more.

But "just" being strong may not be enough to fight on of the nine demon gates by herself.

BUT that's why she's teamed up with Wendy! Wendy can make any partner of her's a lot more effective with her magic. Now imagine if Lucy did a double-summon and Wendy cast ArmsXArmorXVanier on Lucy, herself and the two Spirits.

There won't be many enemies in the series who could stand a chance against that kind of combo, though with us knowing next to nothing about Keith, he could very well be one of those that do. Actually it's even likely.

The factor that worries me a bit more though is Franmalth. If he uses the element of surprise - something for which his body-stretch + power-sucking is pretty well suited - he could be quite devastating, especially if he goes after Lucy and manages to sucks out her magic-power. That would take three of the four fighters out (Lucy herself and the two spirits she will no longer be able to keep here) and leave Wendy against two Demon Gates.
