These options are great but I definitely agree with mrfuji3... This list consider that the game is balanced but it is absolutely not...
Disengage/throw/jump/shove as action should not be an option... They have to find a way to balance these options, then we could talk about increasing the difficulty (harder to shove, ...) Same about cantrips, surfaces and backstab.
It looks like a list to "custom the balance", not to custom the difficulty of a balanced experience.
IE why would you like in an easy experience of a strategy game that ennemies can't use potions, scrolls or surfaces ? They could i.e have maluses or deal less damages... But why shouldn't they use this at all ?
IE backstab should have more or less impact to custom the difficulty... not be a part of the game or not.
I don't really remember all the options of P:K but I love what they did... But it make more sense to me because it increase/decrease the difficulty of the game. The balance is something different.
