Support challenge not working..again

im on the same **bleep**ing stupid challange atm... done 226 damage now after some 8 hours of grinding.,.. you run in, shoot one shot of and you die 99% of the time, and the damage still didnt count becaus it didnt hit the enemys little 1 mm spot on his left nutsack... why do tehy create a INCINDIARY GRANADE LAUNCHER that only does damage it it directly hits the target in its LEFT nut only... its sucha badly made challange, but lets get real, 99.9% of the challanges either does not work, are bugged does not count or only works in bot lobbies, wich they now dissabled becuas yeah they were kinda busted so understandable, but the fact that us normal non bot lobby farmers will most likely never ever now get these challanges done.... i mean it shoots a **bleep** granade of fire... that does no damage,. no aoe. ohh yeah no damage... unless it diorectly hits ONLY 1 target.. meaning you might need some ohh say 200-400 direct hits, of a gadget that has 3 charges, (wich does not matter becaus you are instanly killed when u hit 1 person that may or may not do maby 2 damage....) so meaning you will have to die most likely some 1000-5000 times before you get the challange done becaus its as everyone (Except EA) has noticed, does not work and is bugged and insanly badly designed
