In this case, the choice of "narrative" for the War Devil does, and I might argue should, have an effect on future player/character choices. If a group knows that Besieged Foe has one set of causes, and how to lessen/circumvent them, it could change the entire dynamic of an encounter with a future War Devil (I'm assuming for simplicity that the Alexandrian expects us to extend this line of reasoning to many other powers/abilities, both for monsters and PCs).
I left out a lot of text.
There is a disconnect here ... however the Besieged Foe is fluffed, none of that has
any mechanical effect whatsoever. No matter how you describe it this time, no matter how different you describe it
next time, the effect remains exactly the same. There is
no practical in game meaning to the fluff, that's just there because you added it to add color to the scene.
My read of what is disassociated here is that some players want to "open the box" to discover more details of how the ability (in this case, Besieged Foe) works, and other players just aren't interested.
In 3E, Bull Rush works by one actor pushing another. Strength helps it work better. Size does, too, as does having extra training (the Bull Rush feat). Strength and size both also work to oppose it.
I am thinking (although, I'm not 100% sure if this works, and I can't say how it would work, in detail. I'd probably provide some constant bonus plus strength), a player could ready to assist someone if they were Bull Rushed. Are there rules for pushing someone on icy ground? I would expect a bull rush to work better against someone on icy ground, up until the pusher was also there.
In 4E, my read of many powers is that they are atomic, with fixed results, with much if not most of the model is wrapped in the attack vs defense mechanic, with several different bonuses wrapped in the attack modifier, and several other bonuses wrapped in the defense modifier.
Edit: That sounds like a criticism of 4E relative to 3E, but in this regards I think 3E is already "terminally ill", in that it had already taken many steps to introduce rules that are not explainable (in any real sense). Power attack works for me. Some variations of Cleave don't. (Witness the old "bag of critters" exploit.) AOO's have a lot that is artificial (if I have combat reflexes and an 18 Dex, and I sneak into a room with four sleeping guards, can I AOO all four? How is that being helpless does not draw an AOO? As well, since you could easily draw two AOOs, one for moving, the other for, say, casting a spell, shouldn't I get two AOO's against each of the speeping guards? Or is provoking more active, in the sense of actually prostrating myself to my enemies attack?
