I was recently banned from DDD| ARMAGEDDON - RUSH - ORIGINAL MAPS PBBans #1 for having too high of a K/D ratio. I can understand using an automated system to ban hackers but in this situation I was gunning in a helicopter with a good pilot. My name in BF3 is Vasticus and in the battle report for the match you can see that I was top in helicopter score at the end as well as only 8 of my kills being with a gun and having low accuracy.
