I couldn't be happier that Juvia is alive and I really don't care about the hate. There will always be people who complain, if you don't like it just stop reading it!
To the chapter now, I think it was really good and we can anticipate some good battles, Dimaria vs Brandish will be fierce! Gray completely annihilated Invel (the power of emotions is probably immeasurable) He didn't let darkness consume him too, he wanted to avenge Juvia.
I still believe that Juvia won't find Gray till later, when the Gray vs Natsu happen. He will have the darkness consume him and then Juvia will stop him and show him that END isn't responsible for all the losses in his life.
Natsu was fierce too and I can't wait to fight what's the connection between Erza and Eileen. Probably mother and daughter but why the hate. I don't know how things will turn out but now Mavis is probably safe. I don't think Eileen managed to get Fairy Heart in time. We'll see about that, hopefully Mavis is fine and we'll see a counterattack against Eileen of maybe Zeref!
PS: Mashima actually didn't kill Juvia off, he gave as a bait and we actually believed it. He just made her lose consciousness due to immense blood loss and this is totally plausible. She didn't harm her heart, she pierced her ribs as well so she COULD HAVE DIED from blood loss if Wendy hadn't found her. Mahima made the chapter overly dramatic to lure the readers to the all fake death thing. That's what Gray believed that she died because he didn't even check her pulse, he just held her close. If Gajeel's and Mirajane's "deaths" hadn't happened it could have more impact as a scene, the way Juvia is saved but that doesn't mean it's a lame way or she should stay dead. Just enjoy the damn thing for what it is.
