Hello Devlopers! >.<
For a long while, me and many others that I've spoken to have been feeling that Gjallarhorn doesn't really live up to its true potential and glory, especially after all the lengths you need to go to get it.
At the lvl 75 Cap, Gjallarhorn was an absolutely stellar piece, mainly due to giving Ballad a large boost (+4 Mp/tic with Ballad x2 was just astounding considering there weren't other options to get Ballad+ at that lvl, discounting the Assault Fife in Assault/Salvage).
Now with the lvl 90 Cap, Brd's can now reach "Ballad +2" with AF3+2 Legs and the Crooner's Cithara, both of which aren't exactly hard to obtain at all compared to a Gjallarhorn. (For comparison: Brd's can reach 9mp/tic without Gjallarhorn. This isn't including other forms of Refresh and Gear, so Gjallarhorn's 13mp/tic isn't exactly needed or very special...)
Yes, a lvl 90 Gjallarhorn has "All Songs +3" now (and it can stack with AF3+2 Equipment of course), and many are predicting it to have "All Songs +4" by the lvl 99 Version. The thing is though, Gjallarhorn really only benefits two songs as of now: Ballad and Scherzo.
In regards to Ballad...
Brd's can already get "Ballad +2" without Gjallarhorn, so while adding more Ballad isn't a bad thing at all... It's really not nearly as useful as it once was at the lvl 75 cap simply because there are so many other forms of Refresh/MP Management available to us, through gear/spells/jas/etc. The only other benefit from Ballad with Gjallarhorn is that it's wind-based as opposed to string-based, which is nice when fighting in confining areas (Nothing THAT spectacular...). Don't get me wrong, the boon to Ballad is wonderful, it's just not as incredible as it once was.
In regards to Scherzo...
It's simply better to have Scherzo be used as a Third song with Daurdabla. Gjallarhorn is amazing for the potency of Scherzo, but it only adds a few more % off the DT. It's simply better to use March x2 and then Scherzo with Daurdabla. The funny thing is that Scherzo is already such situational song that it's hardly used anyways.
Gjallarhorn really is just coming off as a glorified space saver, and is just not as useful as its Empyrean counterpart, which is sad to say since Daurdabla isn't nearly as hard to get as Gjallarhorn (And Daurdabla already has the worst path of all Empyreans <.<).
In the end, it's expected that Gjallarhorn will get "All Songs +4" to put it a cut above all the other +3 Instruments already available, but I feel this isn't enough... It's really awful to have Gjallarhorn only be truly useful for Ballad, especially when Ballad isn't as important as it once was.

Gjallarhorn deserves more, and what I think would the perfect addition would be a Gjallarhorn Specific Song.

Similar to how every other Relic weapon gets its very own weaponskill, not to mention having the highest base Dmg of their class, huge acc/att Boosts, Aftermath effects, and even rare occurrences of regular attacks doing 2-3 times more damage.
Gjallarhorn only get's "All Songs +X" that really only benefits Ballad/Scherzo and a bunch of Skill+ that is only currently used to further increase Scherzo's potency (We probably won't even need that Skill+ anyways for Scherzo by lvl 99). I've already mentioned it's better to sing Scherzo with Gjallarhorn anyways since it's better as a third song with Daurdabla. Basically, all that Skill+ isn't even needed, this is even taking the Skill+'s benefits to debuffs in mind.
Granted the Skill+ from Gjallarhorn is also excellent for a Brd's debuff rate on mobs, but here's another funny thing... Landing Elegy on most mobs/NMs is fairly easy without Gjallarhorn and if the enemy you are fighting DOES highly resist Elegy, you're probably going to need Elemental Seal to land it since no amount of M.Acc+/Skill/CHR will seem to let you land Elegy reliably. I could also mention Lullaby/Threnody/Requiem, but Threnody is hardly needed. Lullaby doesn't land on any NM where you'd truly need it, and Requiem is apparently going to be adjusted since it doesn't land on 98% of NMs anyways...
~As for the future~
The Job Manifesto mentioned...
-A JA to enhance our next song that should prove to be interesting and useful.
-A new enfeeble to lower Magic defense that should also prove to be very useful.
I'm sure Gjallarhorn will enhance the MDB song well, and Gjallarhorn will also prove to be useful in buffing what appears to be another Tier of March.
But this simply isn't enough and isn't fair compared to the other enhancements that the other Relic weapons and Aegis have received.
Gjallarhorn at least deserves its very own song. What this song does, I don't know, that should be up to the developers. Something that gives an original, creative enhancement. Perhaps the song could give a variety of stat buffs, Instant Death resistance, Damage Dealt+%, or Damage Taken -% or even just Damage Taken -X (Similar to a Phalanx Effect). Perhaps it could directly heal party members? Or deal direct damage to the enemy? If this song were to added onto Gjallarhorn, it should just deserve to be a stand-out song. Just give it something useful.
In conclusion, I hope I've showed how Gjallarhorn is extremely lacking at the moment and will be in the future if all it receives is "All Songs +4" and further Skill+. It deserves more.
~~Take the below into consideration.
I can assure you, if you were to have a Gjallarhorn Brd be in a standard party, and then have that same Brd be without Gjallarhorn, the difference in performance would be completely unnoticeable in Abyssea and minimal if outside Abyssea.
This is simple unacceptable, especially compared to how noticeable it is to see a player with a Relic Weapon or Aegis as opposed to one without (Not using Empyrean Weapon though, since we all know most Empyrean weapons still sadly rival closely to their Relic counterparts).

Bard has been a job that has been commonly pushed aside to appease the constant complaints of all the DD/Tanking jobs.
PLEASE Dev. Team, just give us some response to the Bard forums. Please show that you still care about the Bard community and plan on giving us some goodies that aren't going to be overshadowed by March x2.
And PLEASE take into consideration how lacking Gjallarhorn is.
Thank you for reading this far if you have! >.<
