Simple as this, throwing knives MUST stay in or the infected are given bullets, your choice. The glitch spots MUST go. And using a glitch spot is technically a bannable offense since you are using something in the game to your personal advantage that the devs didnt intend for you to use.
And having no throwing knives and having glitch spots just tells me you want nothing more to do with that game mode than to boost and get easy kills to pad your k/d.
My vote, hell no. For more than obvious reasons.
