Yep, I played two fun characters using that book. I agree it was a bit bonkers!Magic of Incarnum was one of my favorite 3.5 supplements, actually. My Incarnate's still one of my favorite PC's I've ever played.
It was definitely out there though.
I think my worst purchases were Heroes of the Fallen Lands and Heroes of the Forgotten Kingdoms for D&D 4e. Unlike the Rules Compendium (awesome), the Monster Vault (also awesome, still use the counters now) and the DMs Kit (good adventure), I can't think of anything I used from these books apart from a table for magic armour that didn't seem to appear anywhere else.
