I'm curious why ty's post is considered a wall of salt.
Just because a poster decided to delete their post with "meh"? You do realize that sometimes people are just sensitive and don't act in a mature way and someone else instantly back-paddling or maybe even taking it personal doesn't mean it was a personal insult. And statements like "I'm just dumb and don't understand it" is something that could be a pointer that someone already came in with insecurities.

Ty simply stated that it comes down to mastery, the better you get at healing, the less you panic and feel you need to heal. Which is true. There is no salt or insult in this, it's simply a fact. The first time you see HP bars dropping, you may panic and instantly heal everyone to full. Probably also after the 4th and 5th time but there comes a day when you saw the damage pattern, know it's not urgent and calmly go about your business.
It's not arrogant or salty to say that you have reached a certain level of gameplay where damage just isn't threatening.
And stating that it's important that a role is approachable for novice healers is the opposite of what you accuse them of and there is nothing salty or wrong about wanting to keep that while still giving people that reached higher levels of gameplay more room for improvement without forcing it on novice healers.

If someone feels like they got insulted, chased off or hit with a wall of salt by a pretty professional and neutral explaination why many vet healers are so bored with the role then that is not on the poster but on them. There wasn't a single insult, passive-aggressiveness, disingenuity, salt, accusation or anything that could be interpreted as putting someone down or wanting to ruin their experience.
Would you have really thought they got "chased off by a wall of salt" if it was someone else posting it than ty?

They said they don't understand the issue, ty tried to explain it. What were they supposed to say?
"Glad you're having fun, keep enjoying it! I'll not explain our issues to spare your feelings"?
