RDM cripples mobs, BRD and COR enhance PT members.
RDM gives a PT endurance, BRD and COR give PTs power.

I think this puts a finger on the difference between the jobs, and also why RDM is at a disadvantage in many merit setups. (Relative to BRD or COR, that is. Because those jobs are respectively rare and ultra-rare, RDM still usually has no problem finding a party - many parties are willing to settle for a RDM even if they are less effective for the party's setup and target choice.)

RDM is more focused on reducing the monster's ability to damage the party, while BRD and COR are more focused on enhancing the party's ability to damage the monster. (Not 100% - there's still Gravity, Dia, Elegy - but mostly.) Incidentally, I don't see any mention of one of RDM's most important enfeebles that neither COR nor BRD shares: Silence. A RDM crushes most casters the way a MNK crushes bones; they have especially powerful tools against those specific monster types.

In party setups where the monster is too weak to fight back (either an actual T, something whose stats should make it a T but is rated VT by exp tables, or a monster family that's just hopelessly weak like colibris), RDM is pointless - why bother weakening the offense of a monster that doesn't have any worth worrying about to begin with?

Like many other balance problems (IMO), this would be implicitly fixed if fighting difficult monsters provided as much EXP/hr as fighting weak ones. But it doesn't, so only party setups that are good against weak monsters are considered "successful".

RDM is a constant balancing act, COR and BRD... not so much.
All dispel

All dispel, but not equally well. SMN and BLU can dispel too, but neither has a full set of support tools (although they can contribute quite usefully, it's still a good idea to have one of the big 3).

Although I wouldn't say that COR and BRD are not balancing acts. You have a limited number of buff slots that you have to fill with the most useful buffs possible, and in COR's case you also have timing restrictions and have to trade off pushing for greater buff effectiveness vs. avoiding excessive bust risk. Plus the general balancing of time spent buffing/debuffing vs. time spent pulling which anyone in a support/puller role has to deal with.

Can RDM pull and sleep mobs? Sure, they can use ranged and sleep, but I don't see it commonly, you'd have to give up a slot for phantom/morion tathlum or hedgehog bomb to do so. And just like main healing, not everyone likes pulling, I know COR and BRDs like that.

There's no reason for RDM to use a ranged weapon to pull, unless you are camped in an area with arcana and don't want to fight the arcana (I can't think of any camps that meet that description). Otherwise just pull with a quick-casting spell. (Not a DoT if you intend to sleep the monster at camp, of course.) Pulling spellcasters with Silence is strongly recommended unless you expect them to have shadows, since it starts them chasing you immediately instead of casting a spell. In fact, the ability to Silence pull makes RDM the *preferred* pullers in some situations (e.g. KRT manaburns).

Not that it would really matter if you did give up the tathlum, though. 2 INT and what, 5 max MP? It's only there because there isn't anything better, not because it actually has a noticeable impact on performance.

RDM don't need Utsusemi to pull because unlike COR and BRD, they have full-strength Stoneskin native to the job (and Fast Cast so it doesn't take all day); in some camps /NIN can still be helpful, but it isn't as big a deal as it is for pullers with no other way of protecting themselves.


To return to the original post: If you have more than 2 mobs sleeping in your camp and you're below level 70, you're probably going to get your party wiped as soon as you get a bad resist. Lower level parties generally fight mobs that are actually dangerous to them, and that means resists can happen fairly often, and multiple mobs that aren't quickly reslept will be very dangerous.

Even in merit it should very rarely be necessary to have that many sleeping mobs (unless you just pulled a bst+pet or something like that). As long as you have at least one mob arriving by the time the previous one dies, there's no reason to accept the extra costs and risks of keeping more mobs sleeping, unless you are trying to hog them away from other parties (which is just being an asshole.) The point of pre-pulling is to keep your DDs working continuously, but your DDs can't kill more than one monster at a time without *waking up* more than one monster at a time, which is generally Bad.

Good crowd control is still useful at low levels, but it's mainly for *unwanted* extra monsters.
