How many threads do we all have to make on this issue?
Under the current system, every weapon with a lower DPS than a Dual Cannon gets penalized twice for having a better firing arc: once by having a lower DPS and once by having a lower efficiency (power usage VS DPS).
Yes, dual cannons and dual heavy cannons should absolutely have the best DPS in the game. But should all the other weapons be so inefficient that an already lower DPS becomes an absolutely pathetic DPS when using eight of them (at max power level)? Tactical already gets attack pattern buffs (even more DPS) and DPS abilites while everyone else gets...inefficient weapons.
Sure, engineers get eptw3 but all ship systems are hard-capped to 125 so that doesn't really help.
