So many people on this forum have complained about beams and cruiser damage. So as an experiment I grabbed one of the weakest damaging fleet cruisers and tried to squeeze as much dps out of it as possible.
This ship pulls 9-10k dps in infected space elite.
Doffs are 2 purple conn officers to lower cooldown on tac team and 2 blue energy weapon doffs to lower the cooldown on faw. 1 purple doff to buff directed energy modulation
I actually had the idea also to stack plasma infusers and reduce cool-down on the beams to increase damage/sec but I am only at the captain level so I don't have access to best gear/weapons. It seems to work great from my experience so far. I didn't realize the infusers also increase plasma torpedo as well. Correct me if I am wrong.
