I could do the example with skills instead if you like:
There is a group with a ranger, a cleric, a wizard, and a bard. They decide to recruit a rogue.
The rogue is a "jack of all trades" build who puts a few points into every skill. He has a few points in survival and handle animal, but the odds of him actually succeeding when the ranger cannot are very small, he has a few points of heal and knowledge religion, but the odds of him succeeding when the cleric cannot is again small, same with his few points in diplomacy and bluff succeeding over the bard of his spell-craft and knowledge arcana succeeding over the wizard. But then when it comes to traditional rogue skills that the rest of the party doesn't have, well this guy only put a few points into them as well, so when the group comes up against a difficulty lock or trap, odds are they are just out of luck.
