This sounds like the person just wanted to play Bard, and fed the team some nonsense explanation because none of them knew any better.
The comment about Technical Step is more true, and gets at the general reason not to bring a Dancer to prog. Dancer requires a very well-optimized group to outperform the other ranged, with bursts tightly planned and aligned, a partner who is on point and not going to die, etc. and that simply isn't what a first clear looks like. Dancer is good to have for Curing Waltz, but you do so knowing full well you're taking a hit on damage output.
Bard vs. Machinist is a little more of a guessing game, because with a strong-dps group Bard should win by a little while bringing some help via Minne, while Machinist is better at contributing damage to sloppy runs but lacks upside if you're at a point of needing a little plus-RNG to clear.
