Reason #1-Overkill fanservice
Reason #2-THIS GUY! Otherwise known as the biggest (insert expletive) I've ever seen in anime, Kazuki
Reason #3-A suprisingly high amount of animation screwups, for example, this one that makes Gio look like Exia Gundam
Regardless, about the dubbing, I'm happy about the choices because despite my feelings about the show, I like to still look for quality in the acting for the people who buy the stuff. Plus, it shows that they actually, you know, put effort into casting. I mean, I'm not going to buy it or anything even though I only got 20 episodes in before I was like "I can't take this anymore" but it's good for people who want to.
