When I cleared o4s last week, it was close enough of a dps check that our clear would've been a wipe if I was a machinist instead of a bard. We killed him just as the hard enrage cast completed, so it doesn't get any closer than that.
As people get more gear it will be less of an issue, but boy I'm glad I didn't stick to my machinist for progression in week 1, I would've let my raid down.
