I understand what you're trying to say, but this sentence makes no sense -- and the idea is a little asinine.
To understand how to fix an improve some of the games elements what they need to accept is that their ideas about what the game should be don't mean shit. The teams working on FFXi have, for a long time, had an incestuous love affair with this bastardized view of how the game should work and do their best to forego logical changes that would make it better for everyone involved.
No, I don't mean changes that we beg for, I mean changes that would fix things -- whether we like them or not. The biggest problem is they swing, rather obnoxiously, between listening to the player base way too much and listening to them way too little. There's never a happy median between the two extremes and more often than not we end up with 30% of the games jobs being useless for most of its content.
Since Abyssea released (Which I think was a logical evolution of the game executed rather poorly), DRG, PUP, SCH, PLD, RDM, and RNG have lost significant bearings (some of them even before that). SCH only got back in because of Neo Nyzul, and that's about it. Frankly, in my opinion, serious adjustments should have been made to the entire job system to re-balance it before they even started considering new jobs. Some jobs should have lost things, some should have gained things, and the end result should have been a set of 20 jobs rebalanced for universal usefulness and utility.
Instead we're about to get tossed two more overlapping jobs and system changes we can only hope fix some of the issues -- yet that people who know the numbers behind the game, as you can see above, are already pointing out might not even have that huge of an effect.
Frankly, I wish they'd working on balanced, strategic challenges and content instead of flashy, gimmicky nonsense meant to just waste our time and so poorly designed that it makes a quarter of the jobs in the game irrelevant.
