So, let me get this straight.
My PC kills fifteen orcs with a fireball, and that's perfectly, morally acceptable.
My PC kills fifteen orc minions with a fireball and that's morally bad?
That's some REALLY fine hairs to be splitting. Back in the AD&D days, a fighter with a high strength could instantly kill humanoids on a hit - as in his minimum damage was greater than the HP of the NPC's. That certainly wasn't unrealistic. Any percentile strength was +3 to damage, double weapon specs from Unearthed Arcana was +3 to damage. Broadswords did 2d4 damage - so, minimum damage was 8. Insta-kill for anything 1HD or less. Never minding that any spell that did 16 damage or more would instantly kill any 1HD creature or less, often in pretty large numbers.
Was this somehow morally repugnant? Somehow giving NPC's 1 HP is morally bad but having 2 HP is fine?
Look, hey, whatever float's your boat
@clearstream. You don't like the minion mechanics and whatever reason is yours is yours alone and is perfectly fine. But, I think you're going to have a pretty tough row to hoe to try to convince anyone else that this is a moral issue. And, frankly, why would you even bother? Of all the moral issues associated with D&D, this one is so, so far down the list that even I'm having a tough time finding the point.
