Often, this is not actually the case. High level Swordsages can very definitely burn through all of their maneuvers. And even with Adaptive Style, if a combat ever reaches a point where a Swordsage must recover, he has been less powerful in that combat than a Warblade or Crusader would have been, by default. That's a pretty serious disadvantage.
A bit but not enough.
So another couple of tax feats, or you miss out on that capstone? Great deal.
I'm not understanding this? You mean someone who is already Wis-based could multiclass Swordsage? OK, that I'll buy. Still an unnecessary nerf to Swordsages.
Master of the Nine is incredibly painful to get into, despite being quite good. That's a lot of trash feats. Plus I'm pretty sure Mot9 works out better if you've multiclassed before you take it.
Yes, there are some good dip maneuvers. These are nice. But even a Swordsage is going to have a hard time readying all of them, because you still would prefer to use your higher level ones.
I didn't really say they were gimped, I said this change makes them strictly inferior to Crusaders and Warblades (which they arguably already were, but now there's very little argument about it), and removes the one thing they could do that the others couldn't, which was the Concealment and Teleport tricks that Shadow Hand offers.
Really? I never found it to be. If I ever get a chance to make that Ironsoul Forgemaster//Deepstone Sentinel, maybe then, but at least thus far I've yet to make a Martial Adept that took any maneuvers from Stone Dragon, there never seemed any good reason to.
