Oh yeah, because it feels like "mind control" to some people. In real life, a suitably scary person can glare at you funny and make you swiftly cross the street. But in a TTRPG, few people want to admit that could be a possibility.Protecting other characters is fun, but a lot of people are hostile to such design. I made a suggestion that it is possible to design a non-magical taunt ability that forces enemies to attack you and it spawned, I dunno, twenty pages of somewhat heated discussion.
Tricking or fooling players or NPC's in general is often seen as unwanted- there's always some threshold of "no, you can't convince my PC/NPC to do this thing they don't want to". You see it with people not believing the effects of an illusion spell. You see it with people wanting to carefully curate the effect of a Charisma check, no matter what the score.
And you see it when a mighty warrior roars a challenge, daring his foes to come to him.
Many people want to be able to dictate the results of such actions on a case-by-case basis; if you give someone a mechanic that allows you to, say, force all enemies within 30' to move closer to you on their turn, 1) it better have a saving throw, and 2) it better be strictly magical.
I'm shocked the Battlemaster gets away with his ability to fear or goad a single target, to be honest!
