Stacking pos 1 is a pretty common and effective strategy.

But, For Susanoo Sasuke and Madara, they are immune to ninjutsu and taijutsu attacks respectively.

Does this mean you can just remove all resistance (Sasuke) and defense (Madara) magatamas from them entirely without suffering any side-effects? Since resistance mag reduce ninjutsu dmg and defense mags reduce taijutsu dmg, they seem redundent on Sasuke and Madara respectively.
