Claws exist.

No Gunblades. God no. Stop saying that. I don't want to see everyone with some sort of Squall Lionhart name ruining my server with their shitty roleplaying.

Cactuars are fine, but the original cactuars I wouldn't mind seeing replace the current ones.

Akihiko Yoshida's work in this game is fantastic. We don't need extra hxc trenchcoats and shit. Go play a Nomura game for that.

Wolves don't carry gold.

You can't be serious about making levelling up even EASIER than it is now.

Monster Recruitment would not work unless there was a beastmaster/mediator class/job in the game.

Killing chocobos sounds pretty cool

Overall, I give your post a 1/10. Made like two/three solid points in a wave of awful recommendations.
