Not using excuses, I'm explaining the scientific details.
Fuel Rod Cannons aren't pure blunt force, I'm well aware of that. There is some force, but most of its AP comes from the heat that melts steel and incinerates human flesh. But that's something MJOLNIR shields have some resistance to; punches on the other hand are sheer brute force which is something many character that wear heavy armor tend to have a weakness towards. Spartans still have
9-A striking strength with their strongest body slams and is what is rated on his profile; and that scales to their MJOLNIR plating durability. If I did not include the weakness to striking strength as a weakness, their would have been little to no justification that Spartans had
9-A durability without shields; but
Wall level durability without shields and
Room level to
Building level durability with shields sounds even more absurd. So what's rated now on his profile is still the best option. The other option would be to have no distinction between MJOLNIR shieldings and MJOLNIR plating altogether, but that also sounds absurd since durability in lore clearly drops exponentially when shields are down.
Pistols and Rifles from Halo are stronger than their RL counterparts? Yes, but not by very much. The M6 Magnum was still calc'd at around 1,000 joules; stronger than various real world pistols, but the kinetic energy given the size of the bullet and the
Supersonic muzzle velocity is only
9-C. Same with Assault Rifles being around 3,500 joules; that's still only
Street level+. Sniper Rifles are like 12,000 joules, but that's still
Wall level. Also, all bullets have penetration; just some more than others. Due to penetration,
9-C pistols can potentially harm characters with up to
9-A durability, and Sniper Rifles can harm characters with up to
8-B durability. But for both of those, if they're close to the high end point, they'll need to shoot the eye or something to harm them. I know KIg-Yars are
10-A to
9-C physically with
9-B durability scaling from the marines, but Grunts are
10-C physically with around
10-A durability; any normal marine can easily kill grunts with punches. Grunts surviving plasma is kind of rare; although, it probably depends what class of grunts.
Actually, in Halo 3, All Jiralhanae are described as having energy shields according to
this page.
Anyway, please no more derailing of the thread. If you have any more questions or concerns, I'm open to chat on message walls. You could also politely ask FanofRPGs or Soldier Blue's opinions on the weakness section or the durability distinction between MJOLNIR plating or MJOLNIR shielding; but they both agreed with me last I heard. But please, no more derails on the main topic.
