Ok, since I have several hours to kill while I reinstall the test server client, let's consider this stuff:
To Cover:
- Thf vs Dnc, if Mandau (Neither rdm nor brd are really worth comparing here, the obvious issue is that they think dnc will dethrone thf)
- Rng vs Cor, if Annihilator
- Mnk vs Pup, if Spharai
- Pld vs Blu, if Excalibur (again, not worth comparing rdm numbers)
additionally, sch isn't worth the time, because lolschmelee, and lolclaustrum
Now, Thf vs Dnc is a fair argument, in that dnc, realistically, has a much larger supply of DD abilities, and, on paper, has a roughly equal, or even higher, damage potential. That said, with how intense reinstalling the test server is on my computer (seriously, 1.6~2GIG zip files?), I can't be bothered to math out the specifics, because of the lag, but I may later on.
Rng vs Cor, really, isn't a question of who can put out more damage; that is, unquestioningly, rng, due to the difference in abilities, as well as the still rather obnoxious gap in ammo (rng only ammo has much higher dmg than rng/cor ammo). In fact,
level 99 Annihilator and
level 99 Armageddon have exactly the same dmg (76) and delay (582) ratings, which means that Cor's quickdraw would gain no additional benefit from having Annihilator over Armageddon, nor would cor suddenly have access to a high damage weapon with a different TP return. Now, annihilator is the stronger gun for shooting, yes, because of the 40 r.acc, 30 r.atk, and perpetual Occasionally Deals Triple Damage, however, Coronach vs Wildfire is a very bizarre situation, because Coronach's strength isn't so much it's damage, as that it gives a set (and very low) amount of enmity, and the aftermath lowers enmity generation further. This is very powerful for rng, but really, these days, most cors who are playing DD are doing it with an Armageddon and riding wild fire, and they're not likely to pull more hate than a rng.
Next up, Mnk vs Pup. I've already explained this one a bit; Spharai is a very powerful weapon for mnk, and it would be very powerful for pup as well, but currently, pup is physically incapable of surpassing mnk's damage output in any melee damage situation, due to the way the job works. Spharai won't change that. Besides, Kenkonken would still be stronger for pup. Now, it is worth considering that Spharai is also a defensive weapon, to some degree (13% counter is rather nice, but it's no burtgang, that's a nearly pure defensive weapon), and final heaven is rather irrelevant because its aftermath is subtle blow+10, and anything worth fighting these days has stupid amounts of regain anyway. However, due to pup's evasion, it's not as able to take advantage of the 13% counter, and since it doesn't have any counter damage+ gear, a base counter rate, or much at all in the way of counter gear, it's not exactly a huge benefit for pup.
Finally, Pld vs Blu. Blu's gonna out damage pld, there's not really any question here, because pld's a tank, and blu's a DD. The only redeeming features on Excalibur are it's dmg rating, the 40 atk, OD2.5x, and Additional Effect. Knights of Round is absolute garbage, and the aftermath is a rather lackluster 10 HP/tick regen (which blu can easily beat with spells). Honestly, this poor weapon could really benefit from blu being able to use it; it's not like pld or rdm are actually able to use it to its full DD potential anyway. It's a little depressing, honestly.
Thus;
Annihilator and Spharai would need absolutely no change to their stats if cor and pup (respectively) were added, as it would not influence the damage gap between cor and rng or mnk and pup in any way, shape, or form.
Excalibur is really in desperate need of having a real DD job that can use it, because it's so sad to see such a potentially strong weapon (KoR aside) getting left behind simply because the only jobs that can use it are a tank and a mage.
Mandau, like excalibur, is a situation where yes, if the new job had it, it would likely be stronger than the old jobs. However, like excalibur, this has nothing to do with mandau itself; dnc is simply stronger than thf, brd, and rdm, in terms of DD (though with thf, it's always debatable and situational). Due to that, it really doesn't warrant a need for stat changes or weakening just to allow dnc to use it, that wouldn't suddenly change anything.
As for Ragnarok and Rune Fencer; Rune Fencer is going to be a tank. Tanks do not out damage DD jobs. This is a fact. There is no balance issue giving Rune Fencer access to Ragnarok, especially since it's intended to be the Premier Greatsword job.
For the matter of Sch and Geomancer, they're MAGE JOBS. Back line jobs. They don't melee. How in the world would having access to Claustrum (or in geomancer's case, possibly Mjollnir) suddenly change this? It wouldn't. They don't/won't have access to the gear and abilities required to make melee work. It's really rather silly to even consider it an issue.
thus; SE's logic is absolutely flawed, and they're giving us a cop out answer saying "but we balanced it around the first 15, it'd be unbalanced if we added new jobs" because no, it absolutely would not. Nothing would change, except that the jobs currently not able to use relic weapons would now have them as an option.
Q.E.D.
