To be fair, even if it is a vocal minority we did get a lot of "anime swordsman" and other anime-esue characters in Smash 4, and in some ways it is a legitimate concern. It's not just baby sand pounding, there is legitimate cause for concern. In regards to Lloyd, there's another Namco rep I'm hoping for so I wouldn't want him in based on competition, but even without that I don't think this is the time to introduce him. Even if their games play differently, I think 3 JRPG reps on the pass would be a bit much and definitely a turn off for plenty of people. I'd be more open to Lloyd (or someone like Chrono) on the pass if we hadn't gotten the Heroes (who are surprisingly fun additions), and I definitely think Lloyd deserves a spot on the roster. I just don't think this is the time to introduce him.
Also an unrelated but interesting point I remembered was that Dark Souls was the only non-Pac Man and non-Smash Namco property to get an amiibo.
