User blog comment:BlackWizardZeref/Fairy Tail Chapter 394: Juvia vs Keith Review/@comment-1359322-20140725085545

This week's chapter was bad, just bad. The entire chapter was just rushed. Juvia defeated Keith way too quick, it was like Mashima just wanted to end Part 4 and start Part 5, so he decided to end the entire fight in a simple but very messed up way. And we didn't get to learn a thing about Keith's Curse whatsoever. Then we get the kinda cliche already Tattoo which started as a trend from Cana, Sting and Rogue (though this two are plain failure), Lucy and now to Gray. If another person gets a tattoo, i guess we can call it the plot tattoo.

And END is a flame Demon, Etherius Natsu Dragneel or just another usual Natsu power-up. Either way, i guess Tartarus arc is really like Mashima said, focusing on Natsu and Gray.
