Who had the idea to get 50 kills with the White Phosphorus for a challenge?

I am honestly amazed by this, who genuinely thought it was a good idea to ask us to get 50 kills with such an awful and unrewarding killstreak? You have to do a 10 streak kills for something that barely gives you 1 kill, and it only counts direct impact kills? I mean fuck guys this is so fucking stupid and it's legit my last challenge to get all of them done.

Does anyone have some tips to get this done i need 5 little kills with it and the pointman tactic on ground war is honestly stale and everyone started doing it lol.
