On the one hand I think 'give the PC's a chance to wipe out something in one hit' and on the other hand I'm thinking '1hp for a 20th lvl minion... and the bartender in town has like 15?!??!'
Can someone justify to me why I should keep minions to that measely 1hp? In fact, why use minions at all? Why not just replace them with real creature (take away 4 minions add a real one like the DMG says (I believe))?
Before you guys rush in, can anyone tell me in both mechanical combat terms why I should keep them, and *also* how the hell do you explain this in a roleplaying or 'realism' sense? (note that 'realism' is different from 'realistic' and we all know D&D isn't supposed to be 'real' blah blah let's not go there).
*PS, my own DM who's running KotSF has already decided to give minions more than 1hp because 'it makes no sense' but he has almost no clue about the rules at all for 4th edition so his opinion is 'questionable' at this point.
The claim that minions are somehow unrealistic never ceases to amaze me. Minions are the guys who can be killed with one solid hit from a deadly weapon. Like... y'know... REAL HUMAN BEINGS. What on earth makes them unrealistic? Now, if you were complaining that non-minions - who are somehow impossible to kill without several rounds of beating on them first - were unrealistic, you might have a point.
In game-world terms, minions are guys who lack the fighting skills to go one-on-one with the PCs. Individually, they're easy meat for a player character of their level. They aren't going to make an endurance contest out of it - at best, they get lucky for a round or two, then the PC breaks through the minion's guard and it's lights out. Compare that with a normal monster, which is canny and skilled enough that the PCs can't usually drop it without a few rounds of softening-up first.
En masse, however, minions are dangerous. A martial artist may be able to disable or kill an untrained opponent in seconds, but will still have trouble against a mob.
(It's important to keep in mind that monster stats are designed to reflect how they interact with the PCs. They aren't the universal laws of the world. A minion does not die if attacked by a housecat.)
As for a mechanical reason to use minions? Well, if you want your PCs to face off against a mob, it'll take bleeding forever if the mob is made up of normal monsters. And that forever will consist of the PCs relentlessly slogging through monsters they miss only on a 1, while the monsters wait for the lucky 20. Minions solve the problem. They're very easy to keep track of and their attacks and defenses are good enough that you aren't guaranteed to hit them and they aren't guaranteed to miss you.
