I am not talking about letting you use the daily power again. I am only talking about letting you re-use the "flavor"/narration of the power again.
And that's a problem. Actually, that's THE problem.
The flavor/narration of the powers contain no hook to hang the 1/day limitation upon.
Look, I'm not arguing this for the sake of arguing- this is a real problem.
When I showed the 4Ed PHB to the guys in my 2 game groups, they couldn't understand why something like Villain's Menace couldn't be used more than 1/day. As far as they could see, there was no justification besides "that is the way they designed the game."
That kind of stuff bugs the !#@$^†¥ out of people- obviously, not everyone, but a significant number.
