Some fights are indeed readable to be bad situations. Such as most of the gobbo base encounters if you play yourself in a bad situation. Like walking right into the throne room and having a 4(or 5 with Halsin) vs 10 gobbos with Raz. Or like walking out of the base with the whole party of gobbos waiting to shoot you in the face. These are very obvious bad situation signs.

But yes the phase spiders and the gith knights battle is a complete off shoot that will require you to be just right for the situation, really really lucky, or be good at barrelmancery and cheese tactics.

So yes game needs to work on its region level guiding and locking. You shouldn't be able to proceed to certain areas so casually.
