Well, They've got to listen at some point, I guess. people complained in Shadowbringers, and Square went "Don't worry, we listened. Have Energy Drain back. Fixed, right?"
Then when that didn't fix it, they said "The new healer in Endwalker is going to be more DPS focused. Sound great?" and Sage ended up being a Scholar side-grade with an extra damage button to hit once every 40 seconds.
Then when that did exactly what you would expect it did, Yoshida Antoinette decided to help us plebians with his godly wisdom of "Let them eat Ultimates". And when Healers were notably absent in Abyssos (likely because players of the shiny new sage job finally got bored), we got the ever-iconic "Please just play healer again."
And when Dawntrail's media tour happened, the first dungeon was beaten by a healerless group blind and not even trying to play perfectly, and now here we are. The green river running deep all the way from Valigarmanda to Eutrope.
Can't wait for another two+ years to finally enjoy my favorite MMO role again. Surely they won't just ignore it so they can hype us up before 8.0 releases by saying "we're going to be adding a new healer in 9.0 which will be a lot better, and will be building up the other healers to meet the new one. Please look forward to it."
