They do...but by this same logic, Casters have both an enmity dump (Lucid Dreaming) and an enmity queller (Diversion). DRG and NIN also have other ways to manage their enmity as well (DRG has Diversion and Elusive Jump; NIN can take Diversion and also has Shadewalker to give their aggro to the tank). The only jobs with only 1 enmity management skill are actually MNK/SAM. All other jobs also have options for two, be them 2 dumps or 1 dump and 1 queller.
Personally, BRD/MCH would deal better to have a queller over a dump. It would be more prudent for SE to just remove the dump from Refresh/Tactician, and give BRD/MCH Diversion and its quelling. A support shouldn’t be having to blow their support skills to dump/quell their aggro anyways. I end up using Refresh/Tactician more often or not to dump my own aggro (Refresh less so during prog situations).
Tactician my be up under normal circumstances, but again, a BRD bursts every 80 seconds. That’s a burst in enmity every 80 seconds. A queller would help immensely with that burst, where as an aggro dump, yeah, it dumps it...but then you build it right back up starting immediately after its usage. A queller quells it for 30 seconds—meaning you generate 90% less enmity for 30 seconds. Way better than a flat dump, in my opinion.Refresh and Tactician, especially the first, is usually used on CD (note the "usually" there), and Tactician is normally up there on demand. Again, I would attach an enmity generation reduction to them on top of that. The burst is high, the enmity generation after that isn't. And I can tell you as a samurai, whose burst isn't exactly brilliant, as I struggled not to grab the hate off a tank shortly after the fights began when Diversion was crappy, on Deltascape Savage.
Diversion wasn’t sufficient enough in the beginning, yes, but now it’s 90% reduction in enmity. As a BRD, I’m constantly on the brink of ripping aggro if I don’t have an aggro dump. And there is literally nothing I can do about it. Like I said, even after dumping it, most of the time I just drop to #4 or #5...and then I climb my way back up to #2 before either dump is off CD again.
If you take away piercing, DRG dies. DRG is in the meta now because of the rDPS it brings to the group with Disembowel and the physical ranged jobs. Without the piercing resistance down, there is nothing keeping DRG in the meta. Damage-wise, DRG is performing at about the same level as BRD in terms of personal damage. Litany is great and all—don’t get me wrong—but not nearly enough to offset the raw damage (and utility) that MNK will bring; especially since WARs no longer care for crit buffs since the changes made to Inner Release. MNK would crush DRG if piercing was removed from the game and DRG’s potencies were not buffed to compensate. Dragon Sight provides even less of an rDPS gain than Litany does.The likelihood of having a SAM, a NIN, or a WAR has nothing to do with the fact that PLD and DRK don't have it. DRG isn't only invited for their piercing resistance down, but also for their decent damage on top of Battle Littany and Dragon Sight. So, by that logic, the likelihood of having a DRG is quite high. It's as if they gave BRD and MCH their own piercing resistance down and the next step would be to ask for a Battle Littany kind of skill for themselves.
To give some insight, my highest Chadarnook is 90th percentile at 5752 DPS. My next parse after that was 5335 DPS. What was I missing there? A DRG. My 5335 parse actually had better gear than my 5752 parse. But without a DRG, that was -400 DPS. Just gone.
Uhm, no they wouldn’t. There is a huge difference between a flat +5% buff to your damage that is up 100% of the time, and a buff that gives you +15% crit for 20 seconds every 180 seconds—you’ll see Litany twice in a 7-minute long fight; you’ll have Disembowel up for that entire 7 minutes. There is a huge difference between the two. BRD/MCH would not be asking for their own Battle Litany. BRD/MCH would like their own piercing so that they don’t suffer unnecessarily if a group doesn’t have a DRG. No other DPS job suffers like they do.next step would be to ask for a Battle Littany kind of skill for themselves.
You keep mentioning tank jobs, but I’m talking about DPS jobs. All other physical DPS jobs are able to apply their own resistance down debuffs except for BRD/MCH, and they are the only ones that suffer unnecessarily when a group lacks a DRG. If there was some uniqueness to the resistance downs, then maybe I would get behind leaving it as DRG-only. But, as it stands now, MNK applies Blunt (and is the only one who benefits from it), NIN applies slashing (which it benefits from), SAM applies slashing (which it benefits from), and DRG applies piercing (which it benefits from).
