Incindiary airburst

Another feedback post. The last medic assignment requires 2,000 damage with this gadget. However when I damage or even get a kill with this airburst that you cannot actually change the distance on. A kill is the equivalent to 11 points of damage out of 2,000 so I hope it's just not tracking right because it's already a pretty terrible gadget but this assignment if torture without proper tracking and sometimes not even tracking at all.
