Hasn't there been maths done that show that you cannot clear Ultimate at all without healer damage contributions, and that to beat final Savage tunrs, you need a high-purple/orange team of tanks and DPS, in BIS (ie, needing the gear that comes from said Savage fight) to make up the difference in missing damage from healers?

Looking at my first clear of P12S in week 1, me and my cohealer had 5.6k and 5.9k RDPS respectively. Where are we meant to find 11k more damage, without getting BIS on EVERY player besides the healers, if 'Healers are not expected to deal damage'? For the statement to be true in current raid design, this is the differential a group would have to overcome. It might have been true back in ARR, but it sure as heck wasn't true when the statement was made (Gordias iirc)

Looking again at the video linked in the OP, and re-reading the answer Yoshida gave:



The tone of it, at least to me, seems to aim more for a 'we don't want to force people to do damage as a healer if they're not comfortable', more aimed at the 'feel', and not so much about 'raid tuning'. When they say 'we do not want to make healer DPS mandatory', though, that part seems like it can be construed as referring to raid tuning, and if it is referring to the maths rather than the 'feeling', then they've missed the mark entirely for 6 years
