I'm not even talking about specific job skills, but rather just general.. Executing combos, executing AoE abilities, etc. Wouldn't even need to be centered around any given job, but rather just some quasi-skills/job, like those which are present during battles where you play as an NPC, then you can use these to set moderate enrage timers to help people build the mentality into them that "Hey if you use combo actions you can push out more damage, or if you use AoE abilities across multiple targets you can potentially deal more damage in the grand scheme."
Or.. I probably should've highlighted it like a.. 'Hall of the Intermediate", or "Hall of the Advanced", which doesn't necessarily teach you the core mechanics of every given job, but rather puts you in a position where you need to utilize the core mechanics of the job to achieve victory, which could be, again enforced through the use of an enrage timer, silencing/stunning mobs, or sleeping them. As well as incorporating mechanics beyond dodge the AoE, and putting players in positions where they need to use limit breaks. The game does a good job with Hall of the Novice, but it needs more.. More to try and help people learn the game in creative ways beyond the simple text-on-a-screen active help system they have going right now. You achieve learning and mastery through the use of creative, and challenging tasks- Not through the use of oversimplifying classes, with no real consequence or detriment for failing. Which they seemingly have elected for the latter. Those that wish to learn; shall learn- Those that do not; won't. Having no real tangible point for failure does not encourage learning for those reluctant, with slow understanding, or just an overall lack of accessibility to player-created job guides and resources, and just reflection. Which is a significant problem in anything that isn't extreme primal or beyond since people aren't really encouraged otherwise. Besides, people can be lazy if they're allowed or promoted. But this is just me going on one of my rambles.
