Speaking of which, isn't that the problem people were having with Game2002's stories? Basically that his stories were more or less moralization against yukkuri abuse? Or was it just bad storytelling?
Both, plus his failure to accept constructive criticism.
It's also crucial to note here that this is why you rarely see abyuse comics involving yukkuri like Medicine and Utsuho, given the potential for humans to get seriously hurt according to established fanon rules. The so-called "common types" are the ones most used for those comics because you don't have to worry about shoehorning established consequences into the abyuser's actions.
Actually, there's not much artwork on those two at all. And I can't recall when they've been portrayed as shitheads. But when you say "established fanon", isn't that essentially canon?
Myself, I don't see yus as WMDs. Sure, I think Medi will give you food poisoning and/or contact rash, but she's not the hopping canister of Sarin she's made out to be. To me, Okuu isn't an enchanted suitcase nuke but rather absorbs radioactive material. Dangerous in its own right if the radiation is high or her paste is used for a weapon.
