If it's intended to be a valid strategy, that just makes the game even harder, because avoiding combat is near impossible in this game. In fact, I'm pretty sure it's literally impossible for at least a quarter of the combats.
I also don't see how difficulty can be relative to the person playing it for this game. It's not like there's any skillshots or real-time strategy. It's purely numbers. I guess someone who's bad at math could be bad at this game, but they would be even worse at most other turn-based RPGs.
