Given your lack of pony favorites and/or fanart and your increase of testosterone fueled awesome, I'm guessing that would be traumatic (sadly Dub actors, no matter how talented, seem to always be on the bottom rungs)
You're not bothered as a brony that this scary looking man is voice by the guy who does Carrot Cake and a bunch of other male characters on the show are you? We shouldn't be so testy just because Friendship Is Magic has plenty of big voice talent that did some of our favorite roles and they're now here voicing ponies etc in the Equestria universe.
Who knows what, it might change in the in the future.
Besides the fact that Soarin and Ed are both voiced by Matt Hill, I personally don't care that so many talented voice actors and actresses are in Friendship Is Magic. Do you really care that Brian Drummond is doing both these roles? I wasn't sure if you took issue with many of the cast being played by a lot of big name voice talents or not.
Yeah, I found all sorts of mind fucks. One of the more obvious connections to Death Note is the actor for snips is the same one who plays that secomd guy Light kills. Or Silver Spoon and Misa Misa have the same actor. And even stuff to other shows, Light's actor was Nightcrawler and Gohan.
