or maybe challenge nurfing...

So currently trying to work toward 50,000 bullets deflected... and its getting a little frustrating... taken about 3000+ deaths to 200 kills, and i'm not even at 10,000! just seems bullets go through the shield half the time and that when they not just chaging at you with 1 knife to kill you.

just seems a little unballanced, maybe a stab vest or something needing a few more than just 1 knife to kill and maybe a slightly bigger shield to stop you from getting headshot when directly facing and being dead still. its so frustrating seems like the riotshield has nothing going for it (in pubs atleast) my kdr has suffored majourly maybe i'm doing something wrong i dont know.

So maybe a few hints or tips what maybe i'm doing wrong i want to get this challenge done but i really dont want my kdr to go down any further or maybe you also think there is much wrong with this shield and/or challenge

Thanks
