Experience rates, XP rates or exp rates, refer to the hourly rate at which experience can be obtained through training a specific skill. They are directly related to the amount of experience that is gained via performing certain actions relevant to the pertaining skill, with some skills having favourable experience rates and others having very unfavourable ones. The speed at which experience can be gained in any skill is a large determinant in classifying how "easy" or "hard" the skill is to train, and thus directly determines how many players chose to spend time in training the skill. Although it is worth noting that a skill being labelled as easy or hard is subjective, one might simply say that some skills are less tedious to train than others.
