I would like to see Classes treated as proper, separate "Jobs"

This comes at it's limit when you're looking at skill bloating though.

Well, yes, they can only add so many skills before they'll need to begin condensing things. But there are avenues they can use to tackle skill bloat, not all of which would require fundamental redesigns of classes. Abilities past level 60 could instead take the form of traits, modifying existing abilities, rather than adding new buttons, or future abilities might instead be choices, some of which might replace older ones or the like (which is something Black Mage and White Mage already have to a degree, though it's a bit clunky in execution due to level syncs).

While I want to see some general restructuring of the classes in general, I suspect we won't see anything like that until 5.0 at the earliest, as Yoshi's mentioned that they're aware of skill bloat, but he seemed to think they'll tackle it at the top end of things rather than the bottom, at least for now. (He specifically mentioned having options for abilities as one thing they're considering, which suggests that their thought right now is to curb further growth, rather than chop away at what's already there.)

SE's MMO teams have a long history of making very conservative adjustments, and even the largest adjustments always tend to be built on what has come before. Even the transition from 1.0 to 2.0 was done incrementally, and despite Classes being relegated to the dustbin in terms of game and content balance, the Job system is still in many ways tacked on top of the older system from 1.0, with some adjustments. Even when they were rebuilding the game arguably from the ground up, they maintained many of the core elements from it. I wouldn't be surprised if they're apprehensive about large-scale, foundational, changes, as a big part of the reason this game exists at all the way it does is to say thank you to their Legacy players—a crowd they probably wouldn't want to alienate by straying too far from the original system.

Is that best for the game in the longterm? I'm no soothsayer—but I'd say they will have to make changes eventually to some things, as the system is a little unwieldy and counterintuitive at this point, and runs the risk of only becoming moreso with time. I think we'll have a better idea of where they're planning to go with classes and jobs after we find out more about 4.0's new jobs—will they continue with the "Extra Jobs" label of DRK/MCH/AST? Will we see any new base classes (I think this is unlikely, but not completely out of the question)? Will there be yet another category of jobs instead? It's pretty hard to say right now.
