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))?
Because sometimes you want there to be more enemies and the battle still beatable.
10 enemies at level 1 is not beatable unless some are minions. TPKs happen otherwise (see multiple posts about Keep on ShadowFell module).
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).
Mechanically, it helps fill the battlefield while retaining the ability to affect the battle.
Minions hurt just as much if not more than the standard ones (minions rarely deal one damage so that helps; though they don't Crit it seems).
4 x 4 or 1d8 +2: 16 damage or average 6.
Trust me, four minions ganking you will hurt more.
Realism: The Minions are just as well trainwed, but luck just isn't in the stars for them. They don't hav the divine fortune or ability to urn deadl blows into lesser ones (you do realize since 1st Edition/according to Gygax, hps are just turning deadly blows into lesser, luck, etc)
*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.
Whoa, that would make the battle too rough.
Think about it, the only difference between a Kobold Skirmisher and Kobold Minion is hps and exp.
If you only change hp, than you have guys with same hps and different exp. That is a bad expereince waiting to happen.
I mean, for the player you get gipted on Exp if he only changes hps. And as a DM, he might send more than he should against you.
