Staffan said:If the orc warrior has been living off the land, he should be a ranger (or at least an expert). That gives him six skill points per level to begin with, four after Intelligence adjustment.
Also, I think you are misunderstanding what skill points are supposed to represent. They're supposed to represent training, not talent. Since your orc warrior is stupid as a brick, it just takes a lot longer for him to train himself (or have someone else train him) to do things. He might have natural talent (read: bonuses in other ability scores) that compensate in part for the lack of training, but he'll still have a very hard time learning new things.
OK, I understand that SP's represent training, however, training to jump further would probably involve things such as jumping over and over again, and strengthening your legs etc. I don't really see how intelligence would have any effect over this. Likewise, how do you "train" yourself to have better hearing/vision (for listen and spot)?
Maybe you are right and the character should be a Ranger in the example given, but still, I'm sure there are situations where having your physical based skills restricted due to a lack of intelligence doesn't make complete sence...
