What archery ranger is going to want any melee strike?
This thread is about an extra melee-capable strike for melee rangers, so that is what is provided. It's designed the way it is so that beast-masters can use it if they like while two-weapon melee rangers get the most benefit.
Ah, okay, but the last several posts had been about why Careful Attack was a crappy choice, so when you just posted a power stat-block without any context, I thought you were proposing a general replacement for Careful Attack. As a new at-will for melee rangers, it seems fine.
