Why is Machinist DPS SOOOO BAD?

[RLofOBFL]

I keep seeing mch have less utility than bards. But when I look at the abilit lists seems about equal to me. What am I missing?

BRD has:
Party wide Crit rate +2% with 100% uptime
3% damage buff with Foe's that last 7 server tics or 21 seconds that can be reapplied approximately every 2:30 minutes
20 second 15% direct hit up every 3 minutes
A 45 second instant esuna
A 10% magic or phys vuln for 30 seconds every 3 minutes
A 15 second single target mantra(good for tanks)

MCH has:
A 5 second 10% damage down on one enemy every 90 seconds
A 5% damage up for one or all enemies for 29 seconds every 2 minutes

Then they both also have mp/tp regen and a 20% phys down for 10 seconds in cross role.
