That is just because every single encounter needs a dramatic moment!I don't disagree with your assertion about powers. I very much think they were written with the idea you stated in mind.
But I hope you don't mind me disagreeing that the drama rather loses it impact when people are blowing off their encounter powers not because it would be a dramatic point in the story, but rather because they can. That is what I experienced. Every single encounter, encounter powers are used whether or not they are needed.
Actually, for DMs that don't like the idea of basic attacks killing 1 hp minions and aren't too concerned about the additional bookkeeping, I wonder if the following house rule would work:Killing minions simply is not the same. In the back of my head, I always know that anything would have killed them as long as it did 1 dmg. Minions are great for showing off how powerful a party is, for those "cut through the guards" moments, but they do not really add as much drama for me as a good high-damage spell or move.
Actually, for DMs that don't like the idea of basic attacks killing 1 hp minions and aren't too concerned about the additional bookkeeping, I wonder if the following house rule would work:
HP: A minion has hp equal to 1/4 Constitution score + 2 x (Level + 1); see also minion weaknessThis gives minions basic hit points equal to one quarter that of a standard monster, and requires the PCs to use higher-level powers to instantly kill them. It does shift the balance of minions slightly, but not game-breakingly so, I think.
Minion Weakness
A minion that is hit by a power higher than its level is reduced to 0 hp instantly.
You miss my point - I dislike that the powers are so weak. I miss powers that are on par with the spells and techniques of 3E. I miss the "loads of dice" damage, the crits that take away half an enemie's hitpoint in one blow - at high level. You'd have to make a rule that allows massive damage on PCs and foes.
