Yer. It's not that fellows are much more... er, not-empty, but they certainly are more fun all in all.
One of the reasons I dislike faith trust is that I actually don't want those characters to be out there with me.
That may seem weird to many, and I understand others are exhilarated about it, that's fine, but I don't feel a mighty warrior such as Tenzen would not have something better to do than go level up with me. Her highness Nashmeira (or Aphmau) probably wouldn't frolic around with me even if she much desired for it.
Not to mention spoilers when it comes to Lion, but at least I can go for that boat-ride we spoke of (or at least her alter ego can).
Anyblue, I guess the short of it is: they seem out-of-place to me, be they doppelgängern or not. ^^;
