MCH could feel more machinist-like if instead of summoning Queen and forgetting, you could hop into the mech and pilot it, kinda like how Reaper let's their Avatar take over but ranged combos.

BRD is weird but in most cases bards are generally associated with archery especially in the FF franchise. In other games, like in Genshin Impact, the character Venti has a harp and is a bard but uses a bow to fight. Idk perhaps it's just a way for them to fight while being able to stay ranged? I guess since harps have strings that it kinda goes?

I'm wanting the dev team to take BRD as a more supportive route as well as DNC but they would need to make their support more than just damage buffs.

Lost Ark's Bard has the musically aspect down to a t, so I'm hoping they take some inspiration from that.
