Master: Challenging
Expert: Manageable, about right for most people
Adept: Fairly easy after a few hours of gameplay
Apprentice: Very Easy
Novice: Extremely easy
Basically, people who play skyrim tend to fall into two general groups: People who want a true challenge and have to gimp themselves on purpose in order to make it this way, and people who are perfectly fine steamrolling everything and want their Daedric Armor ASAP and their 100% cost reduction.
Essentially, they should either add a new level of difficulty, or remove all of these cheap exploits that you don't even have to really try at to get in order to make the game too easy. For example, I have a character right now who's enchanting is as high as her one-handed and I haven't soul trapped anything and I have the Warrior stone on that character. They should also cap spell cost reduction at 85%, and not allow people to upgrade past the first tier of Legendary on smithing as well.
They should remove these types of exploits, and if people want the game to be a cakewalk and not present any challenge, they can play the game on Novice.
