God knows (and probably some of you, if you remember the forum during the 2014 reveal!) that I really, really wanted character switching back. It was my biggest dissapointment during that TGS.
Now, however, I see it like LeonBlade: Noctis basically does it all, so I don't really see the point. I guess it's obvious that, if I really wanted the character switching mechanic back, was so that I could play as Cor, who is my favourite character design in a FF in a long time. But considering he's not a permanent party member (it looked like that, or at least a prominent one, during the E3 2013 reveal), I don't really care, as much as it pains me!
I've never bought DLC nor was planning to (apart from Bloodborne and The Witcher 3's ones), but this could be a game I do that with. Let's see how it goes (the content, the timing, the price, if it wasn't originally developed -and then removed- for the base game, unlike certain ME3 one...)
