Amen to that. Three skills for "social engineering"? Two skills for "stealth"? Two skills for "Perception"?
No one would ever pump Hide without also adding Move Silently. Doesn't make sense. So if everyone takes them together, why not combine?
All three social skills are almost completely interchangable. "Look behind you" could be Diplomacy, Bluff, or Intimidate, depending on inflection. Three skills for the same result. Influencing attitudes should be one skill, with the combat effects of Bluff and Intimidate (feinting, making targets Shaken) being combat options accessible to anyone (much like Disarm, etc.).
Combining swim, jump, and climb into "Athletics" makes just as much sense. No one takes swim. No one. But for the 1 out of 50 adventures where it comes into play, it's cool to have characters who can swim. So why not make a generic athletics skill?
Iron Heroes has it right.
