Often times when contemplating what class I want to play I will take a look at my rolls : if they're overall good, I'll generally go something with a little more Multiple Ability Dependence (MAD) vs. if i have a standout score and some ok scores I'll probably be a full caster for Single Ability Dependence (SAD) (or near enough).

For when I do have good rolls across the board, which classes would really benefit greatly from that? Specifically what classes would more greatly benefit from straight 18's than other relatively-MAD classes. Basically, I am looking for a class that has good class features, or would if it weren’t for the MAD they introduce, and thus would be good when you have have all-18s.
