Something I've noticed with post-epic play, is that your individual character levels start to mean less and less the higher up you get. Going from 6th to 7th level wizard is exciting, but 69th to 70th much less so. A concept I've been tossing around for a while is macro-classes, an optional system for super-high level characters, where alternate (PrC) esque classes are able to replace your progression retroactively, and each level of these classes would represent 10x/100x/1000x character levels/HD. This not only cuts down on bookkeeping, but makes each individual level more engaging. The tricky part will be to 1. make sure PC's aren't losing access to critical class features that make everything function, and 2. Try to keep everything at a relatively equivalent power level.
In my concept, these macro-classes would come in 3 power tiers, able to be mixed freely with standard classes/PrC's, and also able to wholly replace your class progression.
Mega-Classes (10x)
Minimum HD for entry: 40 (Which matches the minimum for Lesser Deity)
Total levels available 1-50 (?)
These would be the bread-and-butter of powerful outsiders, deities, and epic PC's. They would be designed to cover a character's basic 1-20 progression in a simplified form in the first couple levels, consolidate the mountain of bonus feats from level into divine and later cosmic abilities, and give broad general power that would make any mortal blush.
Giga-Classes (100x)
Minimum HD for entry: 200 (Halfway between Elder One and First One)
Total levels available: 1-50 (?)
Getting into the crazy powerful stuff now, these classes would represent one's mastery over reality, compressing the mastery that not even the gods themselves could aspire to into the first level and escalating from there. Feats would be compressed into bonus Cosmic and Transcendental abilities, with an Omnific-tier capstone.
Tera-Classes (1000x)
Minimum HD for entry: 2000 (High Lord)
Total levels available: 1-20
The entirety of a universe rendered unto power, these Tera-Classes would represent the aspirations and powers of the mightiest of beings. Want to forge your own realities, or work towards unlocking the secrets of the Omega? This is where you're looking. Levels here would have additional Transcendental and Omnific Abilities, with a Metempiric-tier capstone.
