I know...this pisses me off.
The whole upgrade is pretty lame. It should at least be higher for the post you just gave, you don't see the whinning that would would if T'challa did the same, even if it was explained...you would have haters whinning about.
But if T'challa was just lower level Spiderman...then all that would be out of the window...it would be clear to readers...plus I still don't get why T'challa would risk his life to lift a few more hundred pounds and magic resist...when he could have just build a suit that is far stronger with the same magic wards...for example the Thriced Blessed Armor...being powered armor, instead of just armor.
It doesn't make sense that men died screaming for this upgrade.
