Main reason why I hate it that the sequel is a bi-weekly manga, the fights are shorter than in the original manga. Best example is Jellal vs God Serena or the battles against the Dragon slayer knights.
Seems like Mashima don´t even draw these chapters, his editor does it.
I really think Mashima has not much to do with 100years quest, only make the storyboard and leave it to his editor who can only do the work bi weekly.
Mashima even said, he never planed a squal, his bosses pushed him to do it.
So he said fuck it, gave his storyboard to his editor and they draw it.
I wish Mashima would comeback, but seems like he finished Fairy tail in his heart.
