The problem as I see it is taunt effects that require a target to aggressively close with the perpetrator push the control too far out of reasonable behavior. If the target has a loaded crossbow in hand and the PC taunts him, why can't the crossbowman just shoot at him? A taunt mechanic that allows the target to respond with an attack from where they are would, in my opinion, be a superior design capable of respecting differences in the character of the target. Getting the target to respond aggressively to a taunt is reasonable, but the result of that aggression should be more open than trying to advance into melee. If that happens to be the target's goal in the first place, fine. But if it isn't, then I'm not so keen with it being fine.
Understood. There would (and there actually is in 4e - a Druid Power is quite similar) be good design space for ranged control for a Fighter/Defender to do something to spend a minor action to "mark" a ranged attacker with the effect line: If the target attacks anyone besides the Fighter until the end of his next turn, the Fighter charges the enemy as an Immediate Reaction.
However, what about this side of things. Certainly the ranged attacker considers themselves shrewd and pragmatic and canny and in a tactically optimal position to be at range. They wouldn't fall for such a goad or a ruse even if their failed Will save/defense says they would. That completely makes no sense and destroys his agency. However...wouldn't the Fighter then say the same thing about moving out of melee? Yeah, perhaps he's unnerved, but that is ridiculous that he would just run away like a coward and give up his optimal tactical advantage of melee control. Perhaps shaken (giving up combat advantage or a - 2 attacks or some such)...but run away...a brave warrior act like a coward and simultaneously give up his tactical advantage of melee control? Never. Not even if the mechanical resolution of a failed Will save/Will defense says he would. That completely makes no sense and destroys his agency.
