Hell, that situation pretty much exists with DRK, and I am for SE giving their magic side attention to help steer them from being the WAR with Stun others seem to be content with. Whether or not they'll do a good job on that, though, I dunno. I've kept my head out of there because one "war front" is enough.
DRKs ask for help on their damage dealing side and ignore their magic side because they know that is what the rest of the playerbase-that-is-not-DRK wants out of the job. Else they face the bleak prospects of being one of the those jobs not invited to events. As the game exists now, there just isn't a whole lot of use for DRK being able to be a better caster while ignoring their ability to do damage.

Perhaps you might get what you want if they were to make radical changes in the the effect of new events that catered to that kind of playstyle. The dungeon crawling idea might be a start. Assault was kind of a start, until Salvage was introduced and Nyzul Isle was tweaked. MMM never took off the ground, in my opinion.

I, for one, would like the day to come where you have a 15 person alliance and every person in that alliance comes as a different job with a very different purpose. But I have every bit of confidence that such a utopian day will never come. And so people will continue to ask for what will make their jobs more competitive in the current climate.

For example, earlier in the thread, I suggested the idea of adding spells to RDM that will allow us to enhance the efficiency of pet jobs. Now, the general idea behind what I want is not bad and I know it. But my suspicion is, secretly, others don't want that because pet jobs are not desired, and therefore are not invited to events, and therefore those spells will be "useless". They're going to ask for spells that will allow us to enhance WARs and PLDs and WHMs.

Going off on a tangent for a bit, unfortunately, as a BST myself, I realize that if RDM gets spells like that, it'll only further widen the gap. So in the interest of 2 of my favorite jobs together, I almost do not want new enhancing magic unless we were to get a broad ability to enhance certain jobs in their entirety.
