What do you do to make this game more varied and challenging?
I do this every once in awhile just for the curiosity and variety it will give. What I like to do is do things that I normally wouldn't do. Such as I went an entire prestige using only the default classes. Might not seem like much, but given the right situation, it becomes a challenge on deciding what to do. Such as if there is air support up on a smaller map, do you switch to the sniper class which has CB or try to hide and wait it out with whatever other default class you might have on, etc.
Currently i am using the famas this entire prestige in an effort to see if I can finally finish the prestige headshot challenge for that gun.
Next time I am going to start switching guns ever other match no matter what the map. maybe even switch perks as well, just to see what kind of results I might get.
So what do you do sometimes to make it more challenging?
