I am in the camp of I'd rather it be more difficult than too easy. That said I do have a few issues with the combat AI that I find annoying that if changed would keep the combat challenging but less annoying, such as the f'n Shove nonsense. The Shove distances are way, way too far and just because the player can also do it doesn't make it less annoying to have to deal with. I'm fine with if you happen to place your PC too close to a chasm that you might get pushed off but if I place my guys well away but still get shoved 10m over a cliff it's no longer fun it's just f'n aggravating. /Rant
I've been TPKed more than once by explosion or knockback effects that sent my entire party flying into a chasm. ):
I feel no guilt for save scumming that.
