It made a lot of sense to me. In real life, if I want to build up arm muscles what do I do? I lift weights over and over and over.
Video games are not real life. Many of us have real life jobs so we don't need our games to become a second job.
A fantasy role-playing game is supposed to take the form of a fantasy novel and make it interactive, immersing the player in a fantasy world. Heroic characters in fantasy novels are seldom depicted performing the mundane chores of real life. Why should the video game be any different?
Skill progression should be as unobtrusive as possible. It should occur as a natural consequence of adventuring in order to give the player a feeling of satisfaction and accomplishment, however shallow that may be.
