I started wondering about what D&D would look like if it stayed very close to the SECR model of five classes, skill-and-feat-based casting, and powers, and I attached a document I knocked up in fifteen minutes. Now, I know this isn't compatible with some things we know (paladins are in, barbarians are in, sorcerers are in), but I still think it's an interesting look at what 4E could look like.
