True, but the maneuver does +100 damage, and I'm assuming a 10th level warblade, with a full attack and power attack will be every bit as lethal as a 10th level barbarian. Maybe slightly less because they have to diversify their stats, but the fact remains that with that +100 they'll be dealing more than an equivalent level barbarian every other round, and almost as much as one the other rounds, plus healing... (as long as my point above about being able to deal nearly as much as a Barbarian without using maneuvers holds - and I don't see why it wouldn't: more feats, the same BAB, plus the ability to tap into the fighter-only feats).
Mind you, we're talking 17th level here, not 10th, and any suitably tricked out 17th level character should be able to deal more than 100 points a round - the issue is that the Warblade seems to be able to do that, plus 100 points more than the others every other round, plus heal himself in the rounds when he's not dealing more damage. Sorry, but I don't see how that can possibly be balanced...
