Cheese is mostly just exploiting AI that literally does not respond to basic, dumb tactics. While I don't care if other people cheese, I find the tactics break immersion a lot, even just knowing I could place boxes around an enemy and they would be helpless. I like to feel like the AI will always have some kind of at least semi-intelligent response to anything I do.
I feel like, wouldn't it be more fun if you had to solo the game without cheesy tactics (although, there will always be some level of cheese you'll need to exploit probably)? Properly designed One Man Army will enable that presumably, while hopefully be even harder and more strategic than a cheese run. While it's fun to see how weak of a party can make it through the game, at a certain point the game is a joke if you can solo it with no One Man Army at all.
The game doesn't need to be airtight, no funny, exploity business whatsoever. In fact, it simply won't be with the all the complexity it has. But they should plug up the most obvious cheese for immersion's sake.
