It seems fairly well accepted that the swordsage is weaker than the other two MAs in most situations. I'd submit the warblade is better than the crusader, both due to better access to disciplines and because of a pretty solid recharge mechanic. That being said, I'd like it if the other two classes were on a similar page to the warblade. What are your thoughts on the following:
Crusader:
The crusader picks one of the six disciplines to which he doesn't have access and gains access to it. This choice is made at level 1 and cannot be changed. The idea is to give the crusader a bit more breadth in selecting abilities to fill up his selected maneuvers, since the choice is normally so narrow. This also gives you different areas of specialty, and makes to crusaders feel different.
Swordsage:
Gain full BAB progression. This is because it's a melee class expected to do melee things. It really should have this. The smaller HD, light armor, and recovery method still encourage skirmishing to an extent, but it should still be hitting just as often.
That being said, I still think that this leaves the swordsage behind, somewhat. I'd like it if the recovery mechanic were better, but I don't know what to do. I made a swashbuckler variant for the class that let you recover a single maneuver if you used the Balance, Jump, or Tumble skill during movement for the turn (you could not use that maneuver that turn). It's kind of a quick patch, but it also really only fits for a swashbuckler archetype.
Any ideas here, either?
