this is actually a failure of the system overall. Sure, ToB does what it needed to to make physical combat actually viable. on the other hand, it does not do it in the right way at all.
what tome of battle should have done was rebuild the entire physical combat system so that "Full Attack" was not the only viable option if you were not the Animated Meatgrinder that is a dungeoncrasher fighter or the Shiskkebab specialist that is every single ubercharger as well as the Ubermount paladin. What tome did without suck was to make Weapons of Legacy slightly less suck. OtoH, it still invalidates most of the other classes in the game.
