Challenges are annoying.

I've been playing this game since it has released and i can say that, challenges in this game reduces the game joy. Especially " do something in a match"  type of challenges. It is not about skill, it is not about difficulty, it's just about luck and game time is not enough to fulfill it. I know they've readjusted the challenges but they are still problematic. For example how am i supposed to have "two squad wipes in one squad deathmatch game"? Some of you can say "dude relax if you don't like challenges don't do it". Actually no, i am a player and if you put a challenge on a plate i'll take it.
