well you could have been fighting bad tanks if the beam isnt on you the while time its weak the long the beam is on u with out missing it builds up more and more dmg for ex : 1-2-3-4-5-6-7-8-9 or : 1-2-3-MISS-1-2-MISS-1 so if the tank even misses for a sec a dmg stars over ----------------------------------------------------------------------- now that i think of it the closer you are the more dmg it does
