It seems, like the Combat-System really is an issue here.
Myself, I only found the "Backstabbing" a bit to easy to achieve.
But couldn't this be simply fixed by adding "Attack binding" like in PoE1+2?
This way, a non-thief could only perform an attack from behind, when another companion already engaged the enemy (and this one only has 1 Attack Bind).
Larian should learn more from other TBG like PoE, XCOM or DOS *budumm!*
