Let's keep Character Crossovers from other Square-Enix titles out of FFXIV.

And why do you say that?

Figure of speech mostly. Like when someone says they don't like a certain food or a specific game. It's usually because they aren't good at it or have no skill at it. The OP talks about story integrity. As if the developers don't know what they are doing? If it so happens that Cloud/Sephiroth decide to test their might against my spear then let them come. As I said before, it's not the first time Final Fantasy characters have appeared in other games and when doing so, stayed within lore.
