The feature says
14th-level Path of the Beast feature The beast within you grows so powerful that you can spread its ferocity to others and gain resilience from them joining your hunt. When you enter your rage, you can choose a number of other willing creatures you can see within 30 feet of you equal to your Constitution modifier (minimum of one creature). You gain 5 temporary hit points for each creature that accepts this feature. Until the rage ends, the chosen creatures can each use the following benefit once on each of their turns: when the creature hits a target with an attack roll and deals damage to it, the creature can roll a d6 and gain a bonus to the damage equal to the number rolled. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
This seems somewhat avoidable by having familiars, followers, or the infamous bag of rats, my usual solution to the bag of rats is to just say no, but this feature is already limited by the PC's Constitution modifier, why limit it further with the number of other willing creatures? This limitation seems unnecessary to me.
So what do you think, should I hand wave it? Why? Why not?
Would it be too good if I hand waved the second restriction? Does keeping it contribute anything to the game, or the player's decision making?
