This is pretty much how I look at it.
I feel like this game has reached a point where it's actually hard for me to call a job my "main" job, because I am very much open to jumping ship to something else the second the dev team upend how my current "main" plays. There are definitely people who play the ONE role or the ONE job, and to them, enjoyment of the game hinges almost entirely on the stability of that job. If the devs upend that job, well...... there goes your linchpin of enjoyment.
I really rather not put myself in that situation, so while yes, I lament the current state of healers. I am also just not... really stressing too much about it, because it ultimately harms my enjoyment of the game as a whole. As such, I've just adopted an attitude that goes "oh, they changed it and it's now worse in my eyes? That sucks.... Anyways."
