Let us hypothesize a daily ability that pushes an opponent back a long ways, and another daily that resists forced movement. Let us also hypothesize a monster that can force movement, and a Pit of Evil the monster is attempting to force PCs into. If all a character knows is that the opportunity to use these abilities is rare, it makes no tactical sense to close in preparation for using the abilities in succession. You can go back and ret-con that the character saw the potential for using the abilities a round ago, but doing this means that the character is aware of whether or not any given creature is a valid target for his abilities at any given moment, and that means that the character knows that until he uses the ability, the potential exists, and once he does, it doesn't until he rests.
This is fine; after all, Vanican magic works on exactly this principle. However, Vanican magic is not supposed to be a representation of great skill and training; it's explicitly a use of a time-limited resource. There is no internally-consistent way to spin dailies as anything but use of a time-limited resource from the PoV of the character, because that is exactly what the character sees. A character is aware that he can do something, and once he does, he can't do it again for a while, and that the refresh of this ability is explicitly linked to him waiting for a while (and not getting into fights while waiting). Fluff that describes the ability and does not describe this is bad fluff, because this is how the ability works.
