Just a little story from personal experience and how i feel/felt about using WM~
Enjoy reading if you even take your time to read this :3

As someone who switched from Monk to Bard pre-expansion, having just 2-3 weeks to adjust to the job and playstyle, I should probably be feeling salttier than I actually am.

Having no steady rotation where I just have to press buttons 1-2-3 in order, but a more or less priority system of when to use which skill was already a adjustment I had to make to the playstyle I learned before. Having to watch out for the MP/TP of your members to know when you should play your songs was a bit frustrating at first, since I always forgot to switch the song on or off after I activated it, but I somehow managed to adjust to this as well.

When I first saw the new skills for Bards in that one LL, where they showed them off, I wasn't really thrilled with having a cast timer on my skills since I hate playing Casters and I also knew, that with all the new things I had to look out for, things would get pretty confusing for me since I would've to watch out for when to move without breaking my cast (while trying to look out for mechanics of course) and weaving abilities wouldn't feel the same as before.

After seeing the descriptions for these new abilities, I already felt like "Well, just having all of that mobility and running around will probably still be better." Since I still had (and still have but not as much) that feeling of playing like a Melee-DPS inside of me.

When the expansion hit the servers and I was climbing up to 60 slowly but steadily, I already noticed that I really didn't like using WM just because of those cast timers and how confused I actually got with the priority system while watching out for mechanics and all that stuff (did I already mention that I hate playing as a Caster?). I really denied adjusting to that one Skill.

I also did tests comparing WM vs no WM, and there really wasn't that much of a diffrence for me personally in DPS so I decided not using it at all.

Now post 3.01, I did those same DPS tests again and the DPS with WM was definitely better but I still tried to deny using WM for content, since I really couldn't imagine adjusting to it that well.

So my Raid naturally decided to go do Alexander of course and I never used WM when we tried all those boss fights for the first time. I compared my DPS to that of the other DPS in the group and I really felt frustrated, that I did so much less damage than them, so I finally decided to give WM while we farmed A4 for those tokens.

As expected, I really had my problems adjusting to playing with WM on. I'd sometimes ignore mechanics, sometimes not but instead would break the cast of a skill I almost finished casting and stuff like that.

I somehow managed to deal more DPS than with no WM but it was still pretty low compared to the other DPS. Try after try though, I adjusted more and more and also took more notice of my surroundings. I knew when I could avoid mechanics without breaking my cast, I started to move more in between casts and didn't feel hesitant about doing so anymore and my DPS also got better until I reached the point, where I was finally on par with our other Casters DPS. And I seriously felt happy about that.

Then we started to farm A3 for Tokens and I started to feel frustrated again. Other mechanics, other things to watch out for, the same mistakes I made when I started using WM for the first time but not as much, and lower DPS than all the other DPS yet again.

After some tries and even more adjusting, I managed to do the same as in A4 and raise my DPS to the same level as our Caster or sometimes even be above him, so I felt happy again.

When we started to farm A1 I wasn't really ssure how I'd do but I somehow managed to do pretty well from the beginning on while WM was turned on, when compared to the other turns. I also managed to be on par with most other DPS in our group for this turn. Because of this, our Monk decided to switch to Dragoon for some tries, just to see how far I could push my DPS.... and I somehow managed to be top DPS for most of those tries and I was really surprised and also happy again ^-^

After going through all of this, I don't really hate playing as a Caster as much as before and I also don't mind using WM in the slightest, since I've somehow managed to adjust to it pretty fast in a short amount of time.

Well yeah... long story short:

After starting to get into this "Caster-Feel" and also a feel for WM, I started to like it way more.
I can still understand the saltyness of others but if you don't even try to adjust to the skill then you shouldn't really complain about it.

I also think that some adjustments to make WM even more useful should be made, but not necessesarily those that'll make you "always" be on par with other DPS ignoring diffrent situations.

Some weird ideas I've had that would be "nice to have":

1. A damage buff of X% you gain while you're in WM and Battle Voice is active (been thinking of 5-10% here.... 10% might be too much though)

2. A damage buff of X%*X while Battle Voice is active (X representing the number of active Songs you're playing, which would be either 1 or 2 with WM on in this case. Also been thinking of 5% here)

Why did I have these ideas? Well... WM is still a song that you need to play to increase your damage. It doesn't drain mana like the other songs but it still is a song. So I've been thinking "Why not let it benefit from Battle Voice somehow as well, even if it's just a minor damage increase?"

Like I already said, that's just me having some weird ideas though and might be a bit too much to ask for~
