This addon adds the Intense/Brutal difficulties.
Intense is a difficulty between Normal and Nightmare. Brutal is a difficulty between Nightmare and Insane.
Both of these, in addition to boosting the enemy(33%+2 for levels on Intense, 75%+4 on Insane. +33% for talent levels on Intense, 75% on Brutal.), boost the player as well, granting them an additional stat point every three levels, a class talent point every three levels, a generic point every 5 levels(So, no lost point every five levels, in effect), a Category Point at L46, and a Prodigy Point at L50.
This not only produces a more even curve between difficulties, but also creates an interesting setup playground, where harder to get off the ground setups are easy to get rolling, and skill combinations that are normally not possible, well, are.
Preliminary testing seems to work fine, as near as I can tell.
Achievements are not available, though listed; They're in the addon's code, but commented out, on the grounds that I don't know precisely how the game would react to a bunch of addon-based achievements. Those should work fine, the code looked pretty simple, if someone wants to try to uncomment them.

There's also a commented unlock for Brutal-clearing the game on Intense.
Also, this isn't enabled for the Infinite Dungeon-I swiped the method for Intense/Brutal's stat/etc. bonuses from how the Infinite Dungeon changes its rules...which means I'm not quite sure how they'd interact with the Infinite Dungeon's same changes(Which set comes first/if the game can check for difficulties when enabling the stat changes/etc.). Combine that with the fact that I don't know exactly how the ID works at very high levels(Never really played it) and I think this would be better left to someone with more ID experience.
(Hachem, where are you~

Still, give it a spin. It should work pretty well.
