so as anyone should be able to see  engineer rifle makes no kitten  sense 
it asks for High Risk no reward gameplay by having blunder buss’s  highest damage scale at 250 or less range as well as landing the jump shot  straight ontop of your enemy
and even then all other’s professions double and even triple our burst skill damage from over 1200 range without manually aimed slow arcing projectiles like our mortar and grenades
