Mind wasn't used too much. Air, Water, Earth, Fire, and Body had niches in F2P depending on what the person was trying to do. If I recall correctly, members usually did nature, law, or death if they weren't ZMIing. I'd rather have more than one method of training a skill, and have trade offs between GP/hr, XP/hr, and AFKability. My biggest question is why JaGEx rarely ever modernizing old content? Fiddling with some numbers shouldn't take too much effort.
