Seems like a case of 'hearing from a lot of players' but 'not actually understanding the issue'. Yes healers have a fair amount of downtime - in almost any kind of content, even more so in lower level and 'easy' content. Changing it for 'hardcore' content going forwards will not fix the issue, its a band-aid at most that ignores the main bulk of the game where it actually matters.
It's more a disconnect between the healer playerbase. A portion of the healer playerbase wants to be green dps and another portion the opposite. And since its smarter to appeal to the more casual of the two they make it so healers have less dps spells and lots of downtime, but since the more casual side is more unlikely to do the harder content they make the harder content hit harder and such.
