Ahn - you ignore hit point damage?
I will for some NPCs, particularly if the PCs substantially outclass their opponent and there is no time or security pressure.
Sure. In a number of different kinds of cases. If the enemies are substantially weaker than the PCs-enough to present no real threat-I'll often stop tracking damage (both ways) and just let the PCs kill them (or otherwise do as they wish). That happens regularly.Ahn - you ignore hit point damage?
Sorry, I don't understand. What are you ignoring exactly? Automatically killing NPC's?
Maybe... I think the easiest example would be tripping an ooze. So you've got a 4E Fighter with Spinning Sweep (I think - the first-level encounter power that knocks prone and does 1[W] on a hit) and you use it on an ooze. The DM says, "No, that doesn't work, it's an ooze, it can't go prone." Or what I've done with Come and Get It in the past: "No, the archers don't jump off the wall to fight you." (The dissociation coming from the "encounter power" designation.) In those cases, the "fictional positioning" - the monster being an ooze and the archers in range but on a wall - have an effect on the resolution of your action.
You could get a little more detailed, too: "I use Spinning Sweep so I sweep his leg out from under him, like it says, and then I get on top of him and stab him in the face." Now can the target get up from prone with a move action? You're on top of him, after all. He might have to make an "Escape from Grab" action to get up. I'd do this as part of the NPC's move action - a check against your Fort, or maybe have you make an Athletics/STR vs. Fort attack as an immediate action.

Oh ok -- I thought you might be talking about the thing where the DM never says "no, that doesn't work" but arranges things after the fact so that however you are using it is associated with the fiction (like player:"can I knock this ooze prone?" DM:"uhhh yeah...your Spinning Sweep disorients it and makes it kind of slough over onto its side" Worse: DM:"sure, just explain how that happens"). I think it's definitely true that some forms of mechanical dissociation are more bothersome than others.
"Worse"? What's wrong with allowing the player to specify the effects of his or her actions?
Granted, there's nothing wrong, particularly, with, "No, that doesn't work" but, I find, "Tell me how it works" to be a heck of a lot more fun as a DM.
I don't have statistics, but regularly is pretty regular. Probably in the neighborhood of every other session on average; maybe even every session these days. In many cases, I'm referring to mop-up situations after one powerful enemy is dispatched. I also like to use weak monsters as scenery for powerful PCs and let them feel powerful without wasting time on numbers we know aren't going to matter. It also is important given that my typical battles do present a serious threat. It's important for the players to understand that:You regularly feature combats where the PC's are so much stronger than the opponents that the opponents present no actual threat? What do you mean by regularly?
