I get that they're caused by diffferent monsters, but I can't say that I see the point in replacing Frenzy with something that's almost an exact copy of it. Similar arguments could be applied to a variety of things in the series, but they usually have enough notable differences to set themselves apart (ex. Abiorugu and Glavenus both have flaming swords for tails, but their fighting styles are pretty different), and I can't really see what makes Black Blight unique from the Frenzy Virus aside from the monsters who use it, its apparent inablity to infect humans (I haven't seen anything indicating that it can, though I could be wrong), and the lower amount of cures for it. Well, at least Fatalis gets to live up to the lore surrounding it, and I might retract my statements about it once I see it for myself.
