Henry said:For me, the Book of 9 Swords has a different problem -- not one in terms of it being overwhelmingly powerful (though it is pretty strong compared to, say, Tome of Magic's options), but rather its paradigm; one that is new to D&D, really.
The only problem I've ever had with Book of Nine Swords is the whole core idea of the book -- the "per encounter" balancing. For me, being able to do supernatural over-the-top actions every minute of the day without any resource limitations just changes D&D to a level of the fantastic that I personally don't like. I don't mind the option, but the thing that does concern me is all the people who are raving that "this should be the way the core rules are written." For me, when I want that level of the fantastic, I play Feng Shui. D&D has for me been about heroes with resources who have to struggle a bit from time to time, and who have to measure those resources against the opposition. (I'm not talking tactics or strategy, but the overall story premise of a hero who has to use his advantages wisely.) Encounter-based magics however, never run out, and never put the hero in a disadvantages situation. And if the hero has a maneuver available every single round of a combat (which the crusader, warblade, and swordsage do, because rarely do combats last more than 5 rounds), I don't call it a disadvantage.
Hit points.
