Don't worry, he can take insightful strike again by means of Diamong Mind .

Anyway. Nitpick. It' snot Tiger Strike, it is Tiger Claw.

Also, I think it would be good to change the ranger's fast movement to increments of 10 (+0, +10, +20, +30).

I am not sure how good an idea the four cohorts of the warlord are. Warriors or not. These guys aren't just another four full sets of BAB and hit points. They are 8+ extra skill points to put in things you don't want to give the warlord himself (crafts, Listen, Spot, professions, etc).
