I actually think his 70% defense with the armor is justifiable for these two reasons

1. It's designed to be a quick burst sort of Noble Phantasm, seeing as it used a huge amount of mana to keep up. Siegfried's is continuously on.
2. It still isn't complete negation, and it doesn't work exactly like Siegfried's armor, since he still takes some damage from the attacks it can defend, and he still takes the full damage from attacks of A rank or more, his Endurance nonwithstanding.

I can bring it down to 50%, would it also be fair to say it doesn't use a huge amount of prana to maintain? It still uses a lot of prana, if so, just not a huge amount.

Also, the first part of the Noble Phantasm is just comparing Masamune to the likes of Nobunaga historically that they both liked using firearms. The second paragraph is what actually explains its effect.

[@Cu Chulainn]It gives him a ridiculous stat boost and some pretty solid skills. I believe moving it down to 50 is justified with it as it is. As I told Charak the Fuyuki Grail isn't even capable of bringing in Japanese heroes the only reason I'm considering this as it is is because it's not Oda levels of ridiculousness, and because I need to get this roleplay moving along.

To be honest, a 50% reduction is still a large amount combined with endurance the armor allows for an effective defensive strat as he gets a plus modifer due to his location. Secondly, Its Masumune does he really need all that defense, surely a military genius would know when it's a terrible idea to get close. Thirdly, The mana of manifesting things from the ages of gods (such as the dragon reactor) or the mana expedited through using the breath of the dragon isn't something that can be reduced without hampering the effects of the magic IE the breath lowers in rank or the stat buffs are reduced. Fourthly he is the archer class, defense shouldn't be his strong point.
