In-Game Challenges

I would like to see the in game challenges become catering to each players playstyle and frequently used weapons and classes etc. The game already monitors stats like this so I would imagine this can translate to player specific challenges. The reason being is that if I have a challenge that requires me to use a weapon or gadget or class that I am not used to playing or don't care to play because it's not enjoyable (Assault class is useless), My team takes the fall for it since I'm learning to walk like a newborn giraffe.
