Good news: I got in.
Bad news: the rest of the party makes it difficult to find a niche.
We have:
Cleric/Crusader/RKV
Duskblade/Warblade
Scout/Swordsage
Rogue/Avenger
Paladin/Swordsage
And myself, a thri-kreen Warblade.
Undoubtedly, the RKV will be the powerhouse of the party. The Duskblade should put out a pretty solid stream of damage. Both the Scout and Rogue have any skillmonkey roles covered and the paladin... Well, I have no idea what he will be doing.
So, my new goal is to turn my character into a disruptive force on the battlefield, but other than a couple of high-level strikes, I'm not sure how disruptive I can be. I'd like to find any way I can of causing blindness, crippling, stunning, staggering, etc. that would work on this character. I would go Tripping, but since my Dex is significantly higher than my Str, I don't see that working out too well. Best I have in mind is going with Stormgaurd Warrior and Combat Reflexes to really put on the hurt, but that doesn't really disrupt anyone.
