First: There is a glitch with the Jackel allowing near perfect accuracy from the hip with point fire enhance. There is also a glitch that allows a player to shot while sprinting with the Jackel
Second: The typhoon is over powered with it taking less than 2 seconds to kill anyone with or without auto armor equiped and is within 10m of the shooter.
I do not have footage on it, but I will start recording these issues and posting the footage later.
