There's a balancing act on this that can be done correctly but dev's dont even want to attempt to walk it anymore. If Bard was the only support job and an auto include in every party, I'd agree there's an issue. Or if in the end of 1.0 people would spam 6blms or monks for particular content. But now we have multiple support jobs. That's almost like saying we shouldn't force a need for healers or tanks in content and if 8 dps players want to do all the content, they should be able to.
I always found this argument bizarre, like 80% of the end game players arn't trying to push their version of job composition meta anyway.
The worst part about this is for some reason they just hated on Bard in particular. Dancer does what the Bard players want and HAD for themselves. So clearly they don't mind the role being in the game, they just gimped Bard pointlessly.
