I saw this today:
The second comment there is attributed to the Community user, which is a feature from the last review queue update. And... it's significantly less useful than the first one.* While it is quicker to just click a radio button to select a premade auto-comment, providing specific, actionable feedback is what new users need to become productive citizens of our newly graduated site.
It may be obvious to you (the experienced reviewer) what the problem is, but as a previously new user** I can tell you we do not know even where to look for what to do. Having someone take their time to help you figure this place out is what encourages people to stick around.
We're not such a large site that the premade comments become a necessary evil to keep you sane as you grind through an endless review queue, while countless questions stream in from inexperienced users. We need these new users to grow. If you're in a review queue, "Share feedback" as yourself and write a custom comment. Even if you're not, write a comment when it's needed and you can spare the little bit of time. Please.
* Yes, yes, the first one is from me, so I have some bias here.
** We all were, once. Ah, the memories.
