I was thinking about the phenomenon of "cherry picking" sometimes seen when folks want to powergame/optimize their characters (taking a few levels of many classes in order to maximize character power) and it occurred to me that the xp penalty for multiclassing is exactly backwards: it punishes people for having disparate character levels, and rewards them for having character levels all the same. It should do the opposite; it should reward characters for having a single non-favored class, with perhaps a splash of other non-favored classes. Rogue1/Fighter 2/Barbarian 1/Sorcerer 2 hybrids should be avoided!
So suppose that for every class that a character had within 1 level of another character class, you got a 20% penalty?
A 6th level elven rogue could add a splash of fighter- up to 4 levels, actually, without penalty. But then she would have to concentrate again on her highest level class. She could add any number of wizard levels, since wizard is a favored class. An elven 6/4/2 rogue/fighter/ranger would have to add either wizard levels or increase her rogue level; any other choice would incur a 20% penalty.
A parallel rule could be imposed for prestige classes; you need to be dedicated to a prestige class in order to advance properly. If you take more than a mild deviation (a level or two of another prestige class) after you have advanced a while in your main prestige class, you incur penalties.
So anytime a character has levels in two (or more) different prestige classes that are within 1 of each other, there is a 20% xp penalty for each prestige class involved. Prestige classes whose (non-epic) progression has been completed don't count; they have been mastered, and they don't interfere with a new direction for the character.
This would eliminate the various dragonslayer 1/spellsword 1/eldritch knight 2 type combos that you can see on WotC's optimization board.
Renouncing class abilities:
I would allow a character to temporarily give up the power of a class in order to concentrate studies on another: by giving up all special benefits (including spellcasting and bonus feats, but not BAB, HD, saves or skills), they could ignore that class when computing xp penalties. It would be like 1e, when a human could be dual classed by renouncing the class abilities of one class in favor of another; the other class abilities could be used freely as soon as the new class was a higher level than the old.
An elven rogue 1 could add fighter levels without an xp penalty as long as she gave up the use of rogue special abilities (i.e. sneak attack) until her fighter level was at least 3. Then she could use rogue levels again freely. She could also add rogue levels, as long as her fighter level stays at least two greater than her rogue level.
If an elven rogue 2/fighter 4 decides to pursue a roguish career after all, she could avoid an xp penalty by giving up the use of her three fighter bonus feats (and any feats they are a pre-requisite for) until she was a rogue 6/fighter 4. Then she could use the feats freely.
