I have notice that the Beam are quite Accurate and does more DPS overall than the Pulse once. It also seem that the Pulse one also misses alot of shots too so I would suggest to increase the Pulse DPS by a decent amount to make up for it or maybe increase its accuracy abit? . Personaly I would like them to be more like Eve Online though (Pulse short range high dps, Beam long range lower dps and good accuracy for the smaller guns while less on the bigger ones)
