You must have been playing some truly hellacious Fighters in your pre-4e games if they could routinely give out enough damage to one-shot a giant. Or a dragon. Or even an ogre.
This, to me, is where the minion idea falls apart.
We've been through this in the past.
Ogre. 4hd, 17hp.
Level 8 fighter. Gauntlets of Ogre Power (+6 damage), Weapon Master (+3 damage), +2 greatsword (vs large target).
3d6+11 damage. One shotting an ogre isn't going to be that rare.
There are also two things going on in 4e that you miss. The first is that you add +8 to the to hit roll and all the defences when minionising a monster. This means that
on average (unless there's a wizard about) they take about as long to kill and do as much damage before they go down as they would if you fought them straight.
The second is that the 4e level range is much wider than the AD&D one. In AD&D (as in 4e) PCs are assumed to double in power approximately every four levels (the gap between Hero and Superhero). AD&D basically is played from level 1-10 before you enter the endgame. 4e is played from level 1-30 and scales at about the same rate. You'd never take a monster from Solo (as all dragons are when you meet them) to Minion in a mere ten levels (it takes seventeen).
It sounds like we're in complete agreement about the mechanics involved and how they affect the tone of the game, and our only difference is a matter of opinion. You want rules that encourage fantasy fiction like Conan and Lord of the Rings, and I want rules that are unbiased so we can see how things happen to unfold (regardless of how heroic it may or may not be).
And I've yet to see an unbiassed set of rules. D&D certainly doesn't have them unless you track all the spells for all NPCs, which is way beyond my DMing tolerance.
You don't have to believe it, but it's the design of almost every RPG ever made until 1-page RPGs were designed to promote an whitewashing ideology and censor and mock their publishing. RPG publishers publish game structures to provide game content so it can be used by referees to present to players. This is very similar to how every game is published. It's why adventures are essential to D&D (and unnecessary to storygames, which are built to create a story, not game a game system).
I believe this to be
1: Flat out wrong as my experience with Marvel Heroic, Fate Core, Apocalypse World, Monsterhearts, Fiasco, and even Lasers and Feelings demonstrates.
2: A straight ad-hominem attack on an entire family of game designers who are designing games they want to play.
"Shared fiction" is frankly is Forgite dogma that is irrelevant to all role playing games. It is part of the uniform design which identifies storygames.
Because Fiasco looks like Monsterhearts looks like Kingdom/Microscope looks like My Life With Master. Riiiight.
In fact, there there is a valid point of view that there is no such thing as a shared fiction ever. Stories can only be "shared" ironically. D&D's design was built on this understanding, but also on the belief that people could learn to understand each other better.
D&D's design was based on the idea "Hey, this is cool!" An excellent way of doing things.
So you change the definition of contrived outcome (deliberately created rather than arising naturally or spontaneously) to game mechanic. Are there non-contrived game mechanics for you? Games keep score, track game elements, are designed in almost every way to enable players to act in a gameable situation. Contrived outcomes are the antithesis of this action and the goals of virtually every game designed.
And here you're confusing 90s railroads with storygames. One of the foundational purposes of the Forge was to get
away from White Wolf style low agency games with contrived outcomes.
There is nothing more dramatic about the game because 4e has healing surges as a mechanic.
Once more you are simply incorrect. With healing surges you can hit PCs harder. They go
down in 4e. And then are in danger of Coup De Grace. Going down like that is dramatic, and that you can get back up when you are rescued allows it to happen more.
I hadn't really thought about before but 4e could be ran with just standard monsters. It would play out different than a typical 4e game but I think it could work.
It could. I wouldn't care to - the fights high and low would be a lot less interesting. But there's no reason you can't.
