Congratulations for the new release!
I like most of the changes, however I'm unsure about how the modifications to the overall difficulty will affect the experience. And the Diplomacy bonuses seem too generous.
I will, however, trust your expertise. You're the mod creator, so you know your mod better than any of us.
If I install this version instead of my current one, how the overall difficulty of Hard will be? 170% or 190%? I was enjoying the game with 190%...
And how the mind skill tree will look? Updated? Or will I need to start a new game to see the changes?
Finally, how can I increase the overall difficulty of item upgrades? I prefer vanilla difficulty or 30% easier at most. In general I don't want to be able to upgrade low level items to level 4 and level 5 ones at low levels just because the game is shorter. I can be wrong, but sounds very OP.
