Even if a shortage of competent healers leading to longer waiting times was true, and not some confirmation bias of some people seeing only what they want to see, wouldn't that be a risk of SE, looking at their metrics, thinking "omg making the fights harder was such a mistake ! We have to make everything easier again, nobody want to be accountable for healing these things", "there is so many wipes because of doom debuffs... seems like we can not use this mechanic anymore, the players are not gifted enough to handle it" or "the healers are struggling so much to heal people this xpac, we have to make GNB and DRK on par with the other tanks when it comes to healing, and add more survivability tools to dps jobs !" ?

You know, exactly the contrary of what the #healerstrike is asking for XD

Joke aside, WAR's survivability is not always a bad thing. I did some treasure maps yesterday, and because of bad RNG it did take more than three hours to end up in the final room only one time. Most of the group, not knowing the encounter, did die right at the beginning of the fight, including the only healer, letting only me (as the tank) and one dps alive. If i wasn't on WAR we wouldn't have get the clear, and people would have been so pissed off that some of them would have think twice before wanting to do some maps again, instead of ending up thinking that doing all these efforts did end well.
