How is that relevant? The Action Change Settings are optional, not forced. Or do you mean to say everyone should only play as you do?
Maybe people are forgetting Action Change Settings are optional only, like all the current action change settings. I don't suggest a perma change to "※This action cannot be assigned to a hotbar." Thats not what Action Change Settings are (Wanderer's Minuet and Pitch Perfect, for example)

Also, why you think bard is just spamming burst and ref arrow only (such that the entire class would be spamming 1 button if Action Change Settings gave the option)?
