I don't know about double standards. But I can agree on the dumbing everything down aspect.
Basically, about the only way to look at it is as punishment for the last couple years of tanks and healers acting like glorified DPS.
But hey, new players will never know the difference. They'll never get to experience dying in raids because the healer wanted to #BeLikeMomo. They'll never get to encounter tanks pulling full dungeons in DPS stance only to lose aggro and complain that managing threat is a party mechanic. They'll never get to know what it was like living on the edge.
R.I.P. Stormblood. We'll never forget you.
