Yes, and it being a single target non-benediction is how it should function if they aren't going to revert it to it's Shadowbringers counterpart.
"A lot better" and "just fine" is such a horrific understatement. You are defending what is essentially an invulnerability skill in dungeons that you use every 25 seconds that lasts 8 seconds. So long as you press that one single button and press aoe skills you will. not. die., and more often than not be at full HP, for 8 seconds.
The only healing I've seen people wanted removed completely, including myself, is the party healing on Shake it Off.
Because DRK, for the quintillionth time, does. not. need it. It is not behind on sustain because it does not need it. Nor does Gunbreaker. The people that do complain about it have a genuine skill issue or are complaining simply because they have to put forth a modicum of extra effort or healers complaining that they need to *checks notes* do their job and heal.
The absolute last thing DRK needs is to become even more foolproofed when it's already boring as sin in every moment except when you're bursting.
