Just to echo what SilverObi said, with ffxi’s “horizontal” progression system, it seemed like XI had more opportunity to tweak end game. It seems like XI got better with balancing jobs later in its life. And because we could keep our end game gear for some times years before it was out dated, it made end game less of a grind (at least in my opinion).
Don’t get me wrong some things including some jobs got the shaft (loldrg)
So maybe to answer your question directly- I’d like to see XIV get more of a variety of endgame that isn’t a gear grind.
