[dev] Instanced Raids with classic FF villains and bosses.

I was thinking about this post i made in the past about doing a guild leve with these FF bosses of old but then i thought it might be a better idea to face off against these guys in the form of an instanced raid. Like when yoshi was talking about the underwater temple and such to be implemented, imagine if when you go to the temple you face off against ultros from FFVI in an instanced raid. Or maybe in the crystal tower face off against the two-headed dragon from FFIII. These are just examples of course but i think they would be really cool to implement and would add something very unique to a FF MMO. Also you know about the colliseum battles for PvP coming up. What if a certain FF Villain that has an obsession with weapons suddenly appears out of nowhere and you have to do battle against him? I think this idea would really add alot more fun factor to the game. What do all of you think?
