So, this question is a bit of a shot in the dark, but i'll give a bit of insight. I don't know what the admins plans are for the order of new class releases, aside from what we've already been told regarding the ones having mercantile skillsets as top priority. Some of the older class revamps were terribly done, such as old revamp Teradrim (cocoon edition), super rapier knight Sentinels, and 1 skill is really OP but 99% of our other skills are crap Carnifex. Templar also had this syndrome upon release, but have seen a series of changes and permanent band-aid fixes that have made them viable, but arguably lacking.
We know that the second(?) Sentinel rework is coming with the promise of Tracking and Resins to give them their own unique flavor, so we can sorta rule them out. Teradrim were also taken care of, despite them having gotten a 'recent' revamp during the cocoon era, and were prioritized over the other older classes like Indorani and such.
Based on this, which would you like to see?
