I can understand the no perks challenge. But the no attachments challenge is pretty repetitive, especially after you have already prestiged the gun once or twice and you are then going for gold. I don't use the first few attachments for most guns meaning that I have far more than 150 kills with the gun and no attachments. The challenge I hate is the one for revenge medals. I hardly die when playing but when I do most of the time it is not tactical to go for a revenge kill. Even if so how or why does getting revenge kills denote skill with said weapon? The revenge medals is always the last challenge I need. I complete the double kill and bloodthirsties long before the 150 kills with no perks/attachments.
