Puer's D&D

These are just some ideas I've had tossing around, not necessarily for 3.5 Edition or 4th Edition, but somewhere around there. The idea is to eliminate all the "special" rules, like the Base Attack Bonus progression, the Wildshape progression, specialized Trip and Grapple rules, etc. All these will be folded into the normal d20 skill sets. It also prevents certain types of multiclassing, where (for example) characters pick up one single level of fighter to gain access to all weapons and armor, while still allowing many different character options.
