Challenges MUST be re-worked.

Let's start this off right:  Know that EVERY letter in this is typed with absolute seething RAGE.

Either the "in a single round" needs to be dropped from EVERY challenge or specific challenges need to be re-worked.

10 melee takedowns in a single match when it only accounts for taking dogtags, not ANY melee kill?!  Are we for f'n real?  Sniper headshots of over 150m in a round?  Why are all thses challenges based around NOT helping the team?!

Not only are pieces of class identity hidden behind these, but the most difficult ones only offer "camos" that are not nearly worth the EFFORT.  

"yay, a slightly different tan camo...."

Fix it, all of it.  You WILL change ALL challenges to CUMULATIVE.  Whether you want to or not.
