Prohibit class/job changes inside dungeons

[Enfarious]

You know, and I may have just not seen them all, but, if classes locked (not jobs you can still mnk > pug > mnk and what have you) AND there were sections of a dungeon that had to be cleared for full drops, not speed runs, but rather more like toto-rak in that you have to clear multiple sections to reach the "real" boss.
Unlike toto-rak having each section infested with mobs w/ resistances to different things:
Section 1: mobs absorb magic, strong to piercing, weak to blunt
Section 2: mobs immune to slashing, strong to blunt, weak to peircing
and so on, for let's see, to cover all classes in a fairish way, 5 sections should be plenty
You can optimize parties all you want, but you'll need at least 1 of each dmg type to clear fast, there goes class stacking.
It's no longer a matter of <20mins for last chest(let it be an achievement w/e)
It's now about surving the hordes of mobs that your BLM can't always nuke down, or you MRD can't effectively tank because mobs are immune to slashing dmg...

Derailing class stacking isn't that hard, it's just a matter of making content that requires variety in a party, and for the inevitable "what if the whm/blm/pld/w\e dc's" allowing class changes but not discipline changes would probably be a bit better. So you go in as a DoW you will stay DoW but you can change freely between them, this really only aleviates the stacking issue a bit since you could still go w/ 4 DoW and 4DoM and they switch to what's useful atm, but it still helps a bit.

Since the general tone of everything on these here forums is against class stacking and speed running rewards, not saying don't make speed doable, just don't reward people for it. If you can run a raid in 13 mins good on, you'll get more in than me in any period of time and thus have more opportunities to get drops, but don't punish me because my diverse group takes 28 mins for the same run w/ the same result except the time because we wanted to play jobs we actually enjoy.

Also don't get me wrong, I'm all for trying to out parse people, I'm all for getting the best gear out, and I'm all for bragging rights, hell make dungeon run like BCNMs in XI announce the best run time or w/e, but I shouldn't be punished for not being the fastest group to clear something, except things being timed which is reasonable I shouldn't get 22 hrs to clear a dungeon but again shouldn't be required to beat a certain time just to get the final chest. Think Nyzul or BCNM 15 mins for 5 floors or 29 mins the result was the same, you get w/e would drop for the clear because you cleared it not cause your time was better than avg.

Edit: I don't mean I want Nyzul or BCNM, just using it as an example of what I mean by time limits.
