I both agree and disagree.
I agree that 2H are the most lack luster.
I don’t necessarily think they need super armor though (though I usually switch to 1H if I can’t isolate enemies). I find the normal attacks on 2H (beyond running/smash) to be mostly useless, and opt to use a charge attack over a standard, the timing doesn’t seem to be that different.
That being said, it’s nuts to me that a 2H weapon that moves like it weighs a ton doesn’t stagger an enemy as easily as dual daggers and various other light weapons.
