Machiavelli said:What bugs me is a halfling rogue with a few feats walking up to an ogre chief and being far more successful at intimidating him than, say, a raging barbarian with another creature's blood pouring from his mouth would be.
That's because you're still thinking of the word 'intimidate' instead of the game concepts behind the effects of the Intimidate skill, within the D&D context. The idea is to use credible threats to get an opponent to react predictably in the way that you want. On the 'credible threat' side, bear in mind that in the D&D universe, the raging barbarian could be a 1st-level character, and the halfling a 20th-level rogue. And if the halfling has that many ranks in Intimidate, he probably is pretty high-level, and can do some scary stuff if you cross him. And on the 'create a predictable reaction' side, the articulate character can manipulate the target's emotions much more effectively. The frightened character's reaction to the raging barbarian might be to grab his wand of fireball in panic and empty it in that direction, which is probably not the reaction the bruiser was hoping for. The halfling might be able to rapidly convince him that this is a Really Bad Idea (TM). On these lines, I often think of the 'chess' game between Chewbacca and R2-D2 in the original Star Wars movie (you know, before they ruined the whole thing with sequels and special editions and stuff). Big, strong, dangerous Chewie failed his Intimidate check against the droids spectacularly. After which Han rolled about a 34. "Oh ... I suggest a new strategy, Artoo."
In fact, that's often how I envision the use of Intimidate in a party context. (Don't your adventurers usually have a party?
