Kamamura: "Pretend it's not there." is inherently a stupid argument.
It's not about what you decide to ignore, it's about crippling the unique lore of the world that the author of the book created. Witchers do not use ranged weapons because it does not fit to the style of fighting they are taught, they have witcher signs for that. It's pretty much one of their defining characteristics.
But I guess the console crowd demands another Assassin's Creed/Shadow of Mordor/Whatever clone.
The argument, "it's because consolez!!1!!" is also pretty stupid.
It has a practical use, nuff said.
