I definitely organically discovered the cheese you can do with fog of war, but most of the strategies you mentioned were things that I just did not come across organically. I would love to have more of the debilitating spells that the enemy NPCs were using on me, and I did come across things like Sleep that would rarely work against an opponent challenging enough to deem it worthwhile, especially considering how many enemies you're likely to run into until your next rest compared to how many spell slots you'll have.
