Oh, wait, this is FR, so every tough foe has to be gauged against Elminster or one of the Seven Sisters, is that about it? A 20th-level character is sort of like a "mere" 1st-degree black belt or something?
From reading the posts, I'm not sure if you guys are botherred that the three big E's are weak for their assigned CR, or that you'rre bothered that their CR itself is too low.
Some people do run epic level games. Having these be roughly the level of a balor advanced by two HD is a bit dissapointing for those game needs, particularly when balors can advance much farther just as presented in the MM and not counting adding on class levels (advancement to 60 HD and huge would be what, CR 41?). I would think the elder elemental evils would be solidly much farther in the epic monster CR range and do not think disappointment at statting them as non-epic range monster challenges is unreasonable.
