Great points. WoW was supposed to be "easy to learn, difficult to master". And while I agree that "easy to learn" became more/too difficult, the answer isn't removing all complexity and skill expression.
I always listen to healers from all skill levels and experiences and try to keep a well-rounded perspective. While I understand this point, there are plenty of ways of lowering the barrier for entry without completely knee capping the ceiling by removing all skill expression outside of raw healing buttons.
Are we really just going to dumb down the role as heavily as possible and remove all skill expression so it’s more beginner friendly? Look at support role in league for example. Imagine if they were literally forced to exclusively sit within 10 yards of their adc the entire game and never be allowed to roam or ward or help their team in other ways. Many beginner supports already do that and that’s okay but the beauty is that the more you learn and grow the more you can start expressing your skills in other ways like roaming, warding, etc.
These changes from blizz are removing all of the ways you can grow and learn as a healer in M and making it so there is practically no room for skill expression past the most simplistic form of the role possible (raw hps). That’s not healthy for high end players or beginners or anyone in between.
It’s okay to have complexities in a role that take time to learn and master, as long as the content that you’re doing doesn’t require you to be a master too early, which it doesn’t. You don’t even need to talent into kick as a healer or use targeted spells or track anyone’s available CDs or deal damage until like 12 keys minimum. Removing the ability to grow and expand your character’s ways of helping the team succeed isn’t healthy for anyone.
