He has a point. "Insectaur" is a pretty unusual and highly specific thingamajig. In my whole life, I can remember seeing one in the commercials for those terrible Scorpion King movies, the drow goddess Lolth in Dungeons & Dragons, and also Quelaag in the first Dark Souls.
he doesn't have a point at all. the similarity ends at "they're both aesthetically female insectaurs". that's it. they're completely different fights. because, as i already said, if you say that one is "a shameless clone" of the other just because they're the same "race", then you might as well say that every dragon fight in every Souls game post DeS is a Dragon God clone, ignoring the fact they're completely different fights (and that BoC is a shameless DG clone despite looking completely different). it's a spectacularly stupid line of thought
