A lot of these post SE already answered their question's along time ago but i don't have the time to answer them all so I'm not going to try lol. I'll just put in my 2 cents what I'd like to see

1) I would like to see more bullet's for cor

2) Maybe a level cap of 70 for aby so people would have to maybe level their job (prob just book burn then >.>)

3) Final Fantasy 14 got Battle Chocobo's would be cool if we could do that and maybe use our choco's in battle.
let us get gear for our choco's too.

4) We should get the scroll of rebirth for our whitemage's. (Lets you raise with out having a weak stat kinda like ninja's 2hr move)
