Well, for me, I was stuck in the mode that everything had to be statted out "correctly". If there's a magical effect, it should be based on the spells, right? The 3rd-level hedge wizard in town can't create magical rings, right? (And he can't just be a "hedge wizard", he's a 3rd-level wizard.) You can't just give a monster the hit points and feats you want, it has to be "legal"... right?
This is just plain stupidity on my part, thinking I had to run games that way, but I never was able to get over it. Well, maybe I would have but eventually I stopped caring.
So along comes 4E and it says, "Hey, you're the DM, your job is to provide a challenge with as much flavour as possible. Don't worry about Fey monsters having low hit points, feat chains, or the magical prowess of hedge wizards as compared to PCs. Just use your imagination, follow these guidelines to get the level of challenge right, and kick some ass."
In other words: When I prep for 4E, I feel like my imagination is unfettered.
Thank you for your response.
I can totally see that. 3e, does imply you should be by the rules for NPC creation. I just don't stat most thing sin 3e. Shopkeeper, the only thing stated is like his will save and social skills, and maybe spot to see if he notices slight of hand. I don't bother making him a level 7 commoner or something. So this does not come up much, but if I were designing a monster to fight, well Humanoids I followed the rules everything else no ruels folllowed except what is cool.
Still do for the most part in 4e, i pick a class etc. for an Elven whatist enemy. If the guy is just a human or dwarf or whatever, if fits my playstyle to keep his capabilities mostly the same as the PCs. I don't like having human abilites other humans can't learn for some reaosn. The one exception to this is HP and saves. Whether they are a solo or whatever determines HPs and saves, but what I call active abilites work just like the PCs. In 3e though it was not even implied you could or should fudge the HP. Before I got more lax I had a lot of NPCs who mysteriously rolled max HP.
