As I said earlier, I am getting the war Supporter medal "legit", but simply because when I tried to boost it, the glitch had been patched so I'm sitting at 9/10 waiting on more events.
I however, find it laughable that people are seriously complaining about those of you who abused the War Supporter glitch whether by accident or on purpose and then spend hours idle boosting other medals or playing KOTH on private against Casual bots to boost weapon kills. Its hypocrisy! If you wanna be technicial, and "legit" as you say, you should've played every game naturally and just let the achievement work itself out. Sorry you wouldn't have been able to play any other games until the time Modern Warfare 13 came out, but at least you did it "legit".
