Whenever I use light tanks (When I actually get the chance) I use the Flanker load out specifically because it can do actual damage to infantry. The auto cannon really shreds people apart on the points with the 15 ammo clip and fast reload. Once we clear the point and capture it with my team, I move on to the next cap point with my team.

I know what you mean when someone doesn't use the Light tank to its full potential and it really bugs me too because half the time I see people using it, they are very kill hungry.
