I'm fairly certain any post pertaining to liking the way current healing is will be be rebutted unless it simply is: "I like the way current healing is."
And even those posts might attract a certain ire not particular to the originator but from the people who flock in agreement with the sentiment.
While I like to give everyone the benefit of the doubt way too many people who have said "I like the way healing is, *insert argument*." have been eventually found out for simply being narcissist's whose argument essentially boiled down to:
"I like the way it is, play with bad people if you want your job to be good, I don't care if you're not having fun, deal with it."
Sage was the perfect time for the devs to actually try something new especially with how they were touting it as the "dps healer" the sheer lack of recognition to even call it that or maybe the hubris tells us a lot about how job development in the future is going to be, at least for healer.
While I understand my fellow healers dislike to having a class stay the 'basic b*tch' If the devs ever do make healers good again there's a high likelihood that one healer is going to stay with the original design to appease both sides or in 6 years the 5th healer might be of the opposite current design.
In regards to the population that likes the way healing is, if it was a competition most of them would be "bad" or ranked extremely low, as is the rule of competence.
Incompetence will always be in more abundance than competence.
In terms of the amount of trolls in said group can't say there's anymore than usual in any particular group.
Using the above we could say that most healers who like the way current healing is simply don't understand the way current healer functions in the total or simply don't care to follow the way the game wants you to play it and just have fun with it regardless of consequence.
Such players would do just fine with any change as long as GCD heals remain intact as they do not strive to improve in any particular way or direction that doesn't include their enjoyment.
They don't run anything harder than normal already and groups already do carry them.
So it really wouldn't matter because they simply wouldn't change even if the buttons they pressed were changed.
What would change is people would more often recognize now how incompetent they are by the games standards but no more than people recognize free style SAM and ice mages so no biggie.
I wouldn't put completely misrepresenting the question intentionally or otherwise, giving a non answer in addition to dismissively shutting down said question on the same level as:
"Yeah it could be harder than it was before but not any harder than any of the dps classes or tank classes, healers are the only class that is infantilized by the devs."
Now if you disagree with the above that's a whole other can of worms.
The difference between the two comparisons you make is that one person doesn't understand the question in its entirety and probably gave a non-answer intentionally, has not experienced and probably has no experience in general about healing and is relegating a group to a specific corner of the game if they want to find enjoyment.
Whereas the other group understands both sides of the argument as they have been the noob and risen to the "elite hardcore raider" and are advocating for complexity across the board so everyone can have fun everywhere.
That's just my take though and I'm probably going to be quitting after I finish this next ultimate so~
