Do you know what a SAM does that doesn't want to learn and play the correct Hagakure loop? They don't do it. (Guilty)
Do you know what a BLM does that doesn't like the tighter timing that comes with Transpose lines? They don't use them. (Sometimes guilty)
Do you what MNKs did that didn't want to learn the correct branching combos? Not use them and instead use 123456 on repeat. (Guilty)
If the healing requirements don't get increased as they've stated they won't, that's one thing. But pretending that obscene amount of downtime doesn't exist for many players by also refusing to give us decent downtime gameplay and then telling these players to play Ultimate (where it's the same 1 button spam btw) or go do old alli raids that offer no real reward for running them ad nauseum in hopes of getting a bad party so they can be engaged is tone-deaf, dismissive and ignorant of alternatives.
Because you could absolutely give healers a more engaging dps rotation for downtime and if someone isn't playing healer well enough to manage that they can simply not use it and instead stick to 1 dot/ 1 filler while learning instead of going the full route. Like players of other classes do that are not up for certain intricaties of their rotation.
The beauty of better downtime options like more dps buttons is that it's entirely up to the devs how much of a dps increase using 6 buttons over 1 dot/ 1 nuke is. They could design it in a way that a full and perfectly executed 6 button rotation is only a 2% dps increase over just using 1 dot/ 1 filler after the rework and I guarantee you that the currently bored healers would do it. They do things for less gain than that (*cough*30potencygainDissipation*cough*). While the learning players could still contribute with quite well if they stick to the very basics.
If an entire role can only be engaging in the topmost endgame content or old content with a hilariously bad party for many players than something is seriously wrong with the role - NOT the player. I expect better from a multimillion dollar company than trying to blame the player for their bad role design.
