It's a new thing,  I understand.  But rather leave it alone,  change descriptions to match level of potential pain a person is dialing up.  Like warning "*Chuck Norris* mode, only use if you are really asking for a world of pain."

Which also got me to thinking, is there a huge difference between normal / challenging.  Like is there any best routines monster AI use vs not use ? 

Some numbnuts like me might actually think it still one slider controlling both monster and AI faction difficulty -  but it IS CLEARLY NOT THE CASE ANYMORE.  Because the popup tooltips still say the same thing.
