I think the martial adepts definitely have a place in D&D. Sure, when I first started playing, fighters were fun. Now? I would never play one. I'd get bored after encounter #1. It's part of the same reason I like the new spellcasting classes that have predefined spell lists. Those are intro-spellcasters. Sorcerer is intermediate. Wizard is advanced.
Barbarian is beginner. Fighter is intermediate. Martial adept is advanced.
As far as the balance... I think warblades get d12 because they don't get heavy weapon proficiency. They could spend a feat to get it. A fighter could spend a feat to get improved toughness for the same +1 hp per level.
I really want to play a martial adept after a cursory look. They are complicated enough that I feel like I could get enjoyment out of it for an extended period of time.
When I play D&D, in combat, I don't want to be an android with an algorithm. The crusader probably solves this best, because there is an element of randomness to the abilities you can use.
