Right now job changes are basically falling into two camps: Quality of life improvements or dropping complexity to try and get each job in roughly the same place. Not going to comment on the samurai change since I don't have a strong opinion one way or another with it. Melee feels like it is in a good place right now and the only thing that they might do whether people like it or not is maybe tweak dragoon. Honestly, the one lesson I've learned all these years is that the jobs that are the most complex tend to be the jobs that have the highest dps. Dragoon and Bard are two of them and DRK was another one for a bit there.
