I wouldn't either if it the armour augments stacked additive, but due to some bugs it stacks multiplicative. You could stack up to 6.5k armour (or even more) in cp2077, which makes you virtually immune to physical damage. At that point I would argue that it's beyond what the game was balanced around. Sure, you can still be one-shotted by explosives, but being immune to all other damage (assuming immunity stacking buffs from cold blooded is also taken) makes that kind of broken gameplay to me.
I tried it myself too. Farmed legendaries for all armour slots with max'ed out augmentation slots, crafted all the augments (exploit only works with crafted augments I think). It was pretty funny seeing armour slots multiplying each other and being immune to gunshots and all, but being able to facetank 20 or more enemies at a time is kind of op in my opinion.
