I just got the ELH and have been looking through it. Most of the monsters have hundreds of hit points and enemies of CR 30+ are often in 4 digits. Thus, no party can expect to defeat them very quickly. In this case, the Heal spell becomes amazingly valuable for the monsters. The Red Dragon in the adventure has 1450 HP and the damage that it takes from the Egg would mean very little if it actually knew the Heal spell (which for some reason it doesn't). The only real "easy" way to take down a creature that could cast Heal would be to use Harm on it. Also, Heavily Fortified Armor prevents ridiculous Vorpal/Sneak Attack/Deepwood Sniper combos. The Greater Mantle of Spell Resistance also seems far too cheap. Should it be SR 30 instead of SR 40 (for 290,000 gp)? I missed the big ELH thread, so sory if someone else already posted any of this. Thanks for the help!
