I'd like to see a few major changes to Bard. Most notably a reintroduction of MP usage and a difference in it's utility role.

Primarily i think reworking Bard's utility to be more focused on protective buffs (like shields, tanky cooldown abilities like Palisade, etc.) would be a huge gamechanger over how Bard is percieved and give it a very interesting and unique niche as a support DPS job.

Dancer can be the primary DPS support with big DPS buffs, Summoner and Red Mage have Rez abilities to help out the healers, so giving Bard the role of not a lot of DPS buffs with Tanking buffs to help out the tanks would give it attention and a unique role that isn't just overshadowed by MCH or DNC all the time.

Of course reworking Bard is also something to consider as i personally want it to fit more in the Bardic theme and think changes to the system of Soul Voice (if not the whole song system) need heavy changes and could seamlessly introduce an MP management system that is intricate and interesting while still not detracting from what makes Bard's gameplay style fun (of course addin more oomph to Bard's abilities in sound design is also a huge yes so it feels less weak, but i have noticed quite a few jobs seem to have a lack of oomph in their abilities in sound or feel etc. but that might just be me)
