How's that wording for Blistering Tempo?
Now complete immunity is easier to pass than resistances when you deal less damage than the resistance.
If you deal 10 damage to a creature with fire resistance 20, you need a check result (after penalties) of more than 10 to deal any damage, whereas complete immunity (same penalties) would deal damage starting above 0.
I never understood why the stance progressions of Crusader/Warblade usually take place the level before new stances became available (like the 4th level one in Warblade's case whose progression you are using). You practically are required to dip two levels in another class just to get things to work out right.
How about getting stances at 1/5/10/15/20? You get 1st and 3rd level stances on time, 5th level stance is only a level late, the choice of a 7th or 8th at level 15 (the only 6th level stance is just the Desert Wind one that adds 1d6 fire damage on attacks, that I don't think anyone would take anyhow) and an extra one of any maneuver level at level 20 for the dedicated. And it looks all orderly too.
I kinda like the current progression. It gives tradeoffs and benefits for multiclassing, thus making multiclassing more interesting, one of ToB's strengths.
