Almost eveything in D&D4 design sounds as bad RPG system design to me and a step backwards when compared to D&D3 evolutions.
The idea of "Per encounter" or "Per day" powers or the use of character level in the core mechanism of the game simply don't sound right to me when used in RPG system design because it is so artificial. Using Magic Points is amuch better way to handle
But the fact is, reading preview characters descriptions of the first scenario
here makes me want to read or even play the game, and I understand why they did it this way.
