Rework to the gaining expirience in each ability tree

I really feel that gaining experience with the classes is a real chore, so I think they should add/change the way you gain experience in the different classes. I honestly haven't had a more boring experience than getting the level 100 achievement in mining. I don't really care if they increase the experience needed to max out skills, but at least there should be an easier way to gain experience that isn't just about repeating the same action a certain number of times. I want more parameters added to the equation so that leveling up each skill in the game is a more enjoyable experience.
