Well if that's the case, I take it back, but even so, why would you immediately reject it. I can think of dozens of fights across several MMOs in which a viable strategy was...
- Boss with adds: pull off adds one by one. Pull adds far enough away from original spawn point so that, once adds are killed you can die, reraise, refuel and just go after the boss. Recent example I can think of was a low-man Dodore fight!
- FFXI had several boss fights were a strategy often used was to wipe at a certain point and then have everyone reraise and recover! I've never fought, but I'm pretty sure this is even a strategy used against Pandemonium Warden in FFXI. I used to do this myself when I would solo Brothers ENM - kill first minotaur, allow second to kill me so I can reraise and recover MP to then kill it. There are other examples that spring to mind from FFXI - Ark Angels, Alexander fight, and a fight on an airhsip (I don't remember details of boss).
- Common strategy even used on regular open-world mobs, particularly when soloing something that's proving difficult. Wittling it down as much as you can before running away until the mob loses aggro (or in this game "returns to territory"), quickly curing yourself up, and then going back after said mob whilst it's HP is still low and finishing it off. Whilst it's not exactly dying/raising, it is essentially the same thing (losing hate).
- What about a party that wipes in a dungeon? Should they consider it a loss, or should they raise up and recover and continue, making sure not to get any aggro from nearby mobs during the raising phase? This is a common strategy in dungeons in WoW.
You say it's a disregard for game mechanics, but I disgaree. People have recognised, "hey, moogles aggro to movement, so we can probably recover if we don't move."
Sure, maybe it was discovered as a fluke at first, but who cares? This is a strategy that has been used in MMOs for years and years in several different types of scenario, although the concept is the same - "we can recover, so long as we don't aggro."
Anyway, the whole debate is pretty moot... Regardless of this strategy, most people who want will have moogle weapons in a couple of months anyway. At least in this scenario people would have obtained those weapons by using two different strategies, rather than everyone just copying each other with Ifrit.
