This question states that being able to Feint from 30 feet with Grovel is an "unambiguous and clear advantage".
I do not see it. Yes, you can make the target flat-footed from afar, but only against your melee attacks.
So now instead of Striding to the enemy, then Feinting, then Striking, you can switch the first two actions. Where is the clear advantage?
Even if you have a beneficial way of combining a Feint and a Strike, or a Feint and a Stride, it does not help, as the Grovel feat does not modify Feint, but is its own action.
What am I missing?
(this question is not about the Will instead of Perception issue, that is well covered by the answers there)
