Aside from the notes above regarding 3.0 vs 3.5 and CR being a guide, I think it is worth noting also that tactics dictate not getting in reach of anything that primarily is skewed toward pounding you into a pizza. The worst possible tactic to use on something that mainly fights hand to hand is is physically much stronger than you is to close to melee. If it closes with you, well, then you do what you have to do. But spells that blind/entangle, etc and ranged weapons are the key to such encounters. Did the players take this approach in any of the tests?
