Come now, a good player will evaluate the circumstances objectively and determine based on rigid criteria whether a situation will support their side-act.
Having a Mjollnir doesn't suddenly make WHM a DD job, although it is a significant boon to its offensive capabilities.
The thing that's most important to remember is that meleeing should supplement your normal duties, not distract from them. My DPS estimates are higher than a good WHM will achieve because they necessitatively ignore such activities.
There's no doubt that the niche is stronger than its ever been, but there's also little reason to realize this niche. There are no merit parties where the infinite MP and additional damage improved your party's efficiency. There are obviously events where it works, but there are also probably better jobs you could be doing them on. But if you're playing to your maximum potential and your group values your contribution, then I see no problem with it.
I think people probably think I'm a lot more rigid and mathematical than I really am sometimes. I'm not afraid of numbers, that's all. I realize that even in ideal situations, except versus blunt weak enemies, my Dancer will be at least slightly ahead of my White Mage.
But, in a situation where I might have gone Dancer with one or two friends, there's a strong chance that circumstances will allow for the combination of my support and damage to surpass what I could have provided on Dancer - even though ultimately, melee WHM and DNC are slight variations on the same fundamental niche.
Is it really worth the 250mil I'm going to end up spending on it? No, not really. But, comparatively I haven't spent all that much time or strife on it and I've found ways to take ownership of the situation and make it special to me.
It's also been a blast devising optimal sets for something - and I clearly admit - a job for which I am not used to doing calculation
