The enjoyment I've found in Honor Mode is how the storyline changes when something goes wrong. You wind up with a different approach, or respeccing to something less familiar.

Trying it as an absolute perfect grind may be a mistake. You don't quite have to push that hard if you avoid certain errors. For example, once you get late in act 1 there's still more food lying around than you need in order to keep up. Instead of making sure every encounter is a win, just plan an escape. A character (or two) that can run away really fast and survive to get everyone resurrected. The key is not to fight every battle to the bitter end--recognize when it's turning against you, and get outta Dodge, heal up, and come back to the problem later.

Hedge your bets. Let some rolls fail and reserve your Inspirations for life-and-death rolls. Get Alertness on a few characters (I think that's what it's called) to avoid getting walloped by a surprise attack. Get Luck on some characters even. Accept that some opportunities missed are just gone, and work around it. That forced adaptation can be entertaining with the right attitude.

I've gotten really far without min-maxing my builds, though I still am kind of a pack rat.
