Bruh, what the fuck?! You might as well have Dyne not even be there if you basically remove all of his tendencies just to make him insane because of JENOVA Cells(Seriously, what the hell is so wrong about Dyne becoming a massive nihilist who wants to kill everyone due to how fucked up his life ended up, even his own daughter along the way? Like sure, he kills himself in the original game but it was BECAUSE he realized there was no way in hell he would want Marlene to see him as a father after the shit he's done). And I already heard about the Cid shit, that's just ridiculous when that was the whole point of his character development(He shat on Shera only BECAUSE he believed she fucked everything up for him only to find out later on she was exactly right when he was about to die for it).
