If you don't want to be demoralized by the Intimidate skill you could invest in the Sense Motive skill. I don't find the Intimidate skill unfair, but I do think the mechanics for using it are a little clunky. I'd rather see the results based on a Will save since the monster's bonus to Will saves is a number that the DM is almost certain to have handy whereas very few DMs seem to calculate the DC to Intimidate a monster before somebody attempts it even if the party has a PC who uses Intimidate in most fights.
Sometimes DMs are also reluctant to tell the players a monster's hit dice and Wisdom modifier. This can cause the calculations to take a while since I often have to tell the DM the formula for calculating the DC repeatedly. There are similar problems with using Bluff for feinting (though maybe that would be better opposed with a Reflex save)
