The long-expected party... I mean post. (Sorry, reading LOTR for about the billionth time.)
I don't think the usefulness of DRG pre-50 is much in debate, it seems to be generally agreed that they are as valid, and in some cases a more valid choice than other job types. In this area the maxim holds quite true that player skill and equipment are larger factors in usefulness than job and race, given some common sense. (Relying on your blm with a scythe to do all your melee dd might not be the wisest decision, for example.)
And if my memory is serving me correctly (and it may not be, I'm very tired) I seem to recall pting with Zariko a time or two, and assuming I'm thinking of the right guy, they were enjoyable and very profitable experiences.
Anyway.
The issues seem to be SC usefulness and post-50 DD power.
By way of disclaimer I should point out that most of this is not from personal observation but simply comparing the numbers, so to speak.
Disregarding SC3's for a moment (as they have more bearing on the post-50 stuff, here's a breakdown of what SC2's DRG can partake in, and when)
And for the sake of arguement we'll disregard the impact of Wheeling Thrust and Impulse Drive on SC2, as these play a larger role in SC3.
Fusion (Fire/Light)
DRG polearms can't open these ever. Period. But they can close them with Thunder Thrust, Raiden Thrust, Leg Sweep, and Skewer. Admittedly Thunder Thrust, Raiden Thrust, and Leg Sweep are kind of meh. Skewer's nothing to laugh at though, from what I understand.
Fusion is somewhat of a weak point for DRG until they get the 200 weapon skill needed for Skewer.
Fragmentation (Thunder/Wind)
Sadly, due to the way renkei function mechanically, DRG is not very useful with this SC either. They can't open it until Impulse Drive opens up, but then you'll have better uses for that particular WS. They can close it with Vorpal Thrust, which is decent, but there are better ways to close a Fragmentation, honestly. This is a DRG weak-point admittedly. No shame in admitting it.
Gravitation (Earth/Dark)
DRG shine here, as far as closing a renkei goes. They won't be able to open one until they get Wheeling Thrust (better uses for that too), but when they close one, they close it with finality, with Penta Thrust and Skewer.
The arguement runs that you rarely have a use for Gravitation when xping, but Crawlers come to mind as a valid choice. Honestly though, this is more the fault of the cookie-cutter way we all tend to play this game. In my personal experience, you can xp in many other places than those everyone seems to go to. Statics have a lot of freedom here, as a good one can look at their strong and weak points and cater their xp fodder choices to their strengths. Just because Gravitation is not useful to your party does not mean its not useful to others. Admittedly there are fewer classifications of mobs that are weak to Earth and Dark, but they are there.
But I digress...
Distortion (Ice/Water)
Speaking of useful renkei, I have to say I've always been fond of this one, because admittedly Ice and Water weaknesses are remarkably prevalent in the game. But since I just dismissed arguements of Gravitation being useless for related reasons we'll disregard this. Nevertheless DRG have much to offer here. You'll never see them close a Distortion, but just about their entire ******* can open one. Double Thrust, Thunder Thrust, Raiden Thrust, Vorpal Thrust, & Skewer.
Skewer's about one of the most damned versatile WS in the game, usable in three different SC2s. The only other WS I know of that do that are the AXE skill Spinning Axe and the GUN skill Slug Shot.
Generally speaking no weapon is great at everything. For example, you'll never see H2H weapons in a Distortion, or Scythes in a Fusion, at least not until H2H Dragon Kick and SCY Cross Reaper and Spiral Hell open up, but those will be busy elsewhere. =P
Still, if I were to provide rankings, from most potent to least, I would have to say
Gravitation
Distortion
Fusion
Fragmentation
Unless I'm way off target, Gravitation and Distortion pretty much cover about half the mob classifications in the game.
Before I hit up the SC3s, I thought it might be prudent to point out something worth knowing. As far as heavier weapons go, PLM are nothing to laugh at. They don't hit as hard, but they're faster. I think the words "personal preference" would apply. A SCY, GSD, GAX, or GKT will hit harder, but the PLM will hit more often. Parser stats might be interesting to take a look at.
And you know, I haven't seen the high-end WS in play, but I have to say I like the sound of the PLMs final 2, compared to those of the SCY, GSD, GKT, GAX, and BOW. You can look them up yourself if you aren't familiar with them, and again, this is simply my impression of them, given the attributes I see listed for them. Of all these weapons and their last two weapon skills, Impulse Drive is the only one that hits multiple times, and Wheeling Thrust punches through mob defense, dependant on TP.
H2H admittedly is also quite nice, as Asuran Fists hits 8 times. Pity they nerfed multi-hit WS TP acrual so long ago. That would be entertaining, to say the least.
Anyway.
Given that, DRG can be in a LIGHT Renkei with Wheeling Thrust and a DARKNESS Renkei with Impulse Drive. Diversity = Yes, please. The same can't be said about some of the other common DD weapons. Of the ones I've discussed. H2H, GSD, and GKT can participate in both. GAX and SCY can only do DARKNESS, BOW and GUN can only do LIGHT.
So regarding SC3s, it seems to me that DRG can perform at least as well as any other job, and has the benefit of being able to do so with their best weapon. The same can't be said of some of the other DD jobs, and RNG are pretty much completely excluded from DARKNESS SC.
I dunno, maybe that all sounds like nothing but tripe, being as it is merely my conjecture after having done some research and a lot of thinking at work tonight. Very little personal observation.
But at the end of the day, it seems very clear to me that it isn't the balance of the game that tends to exclude DRG, but merely how we chose to play it as a community. And that's an unfortunate thing.
Maybe my experiences later on in the game will change that opinion, but as it stands now I see no valid reason to view DRG as anything other than a viable option for DD. And plus they're just damned sexy, which I think is the real reason everyone else hates them. Jealousy. =P
In all honesty though, I doubt this debate will ever be resolved, unless some enterprising individual takes the time to collect parser stats on DRG compared to other, more common post-50 DDs.
And if that information indicates in a conclusive manner that DRG are gimped, as many feel, then fine. But without such conclusive proof, touting your opinion based on experience as a truth, and heaping mockery onto the heads of those who don't subscribe to your particular truth is inappropriate in any forum. Especially one about a game.
(I just couldn't resist one final comment regarding the tone of some prior posts. =P )
And there we have it. Another horrifically long-winded post by me. I think if we ever have a contest to see who can talk out their *** the longest, I'll win by several miles. ^^
(That is, if you can get me to stop talking long enough to tell me that I won.)
Nitey-nite. It's WAAAAAY past Nata's bedtime.
