An additional "Hardcore" or "Seasoned Tactician" mode with increased difficulty would be super cool.
Limit saving the game to long rests, no quicksaves allowed
Critical failures (and misses) should have more consequences (maybe add a 5% chance of breaking the weapon and requiring having it repaired)
Weapon and item degradation sucks, its just extra boring crap to take care of repairing. Better to have a demoralised effect or something after critical misses. No quicksave is also sucky, too much to be repeated due to crashes and whatever. That would definitely need to be a toggle option.
