When we get through the classic jobs, I'm sure theyll shove that gunblade that everyone wants somewhere, or something else, hell musketeer was originally gonna be a chocobo rider with a gun, but im not too concerned past that point, call it nostalgia but id like to see more jobs we all know get put in before we run out.personally, though - as far as tanks and healers go, I think they would have the hardest time developing and balancing either, and im not too sure what AST was supposed to be to be honest. for healers theres some spells that do exist may be op but would handle healing a little different, from ff12 - bubble and reverse, also a tp healer. for tanks? thats a little bit harder because well tanking is a very precise thing in this game. It would require a ton of thought, maybe an overhaul to the current system for them to be able to make one thats refreshing and deviates from the template as is.
