I never put much trust in insightful reflexes without splashing of 2 rogue or monk. By end-game, those few reflexes won't matter against stronger spellcasters like drow priestesses and the wizards in the high road. You can get it early-mid game, but once you hit 20, I think the feat is better exchanged and spent elsewhere. Even with high intelligence, you still won't be evading excessively like rogues or monks, and the feat is better used on a spell focus, spell penetration, or metamagic.
This post is horrendously wrong. Newbies, don't listen to this at all.
AHHHH, it's a necroed thread!
Though even back then it was wrong...
