And where are your numbers, wnmnkh?
I mean, there have been tests of cap ship vs cap ship combats, but no proper dps tests so far.
What times did you use for weapon refire rates, did you check all guns, or only front batteries and so on.
I do not want to question your observation, just curious how you get to these results.
But well, after doing some research... you are right. I guess you used a similar source for your conclusions:
I use this sheet for reference... I am not that sure if it is correct, that's it. The weapon arcs are also tricky. The Egg seems to manage to bring most weapons to bear at any angle e.g. Maybe Vasari have the advantage to use the weapons at their disposal much better for focus fire than other races, no clue. The Sova Carrier e.g. has to fire broadsides to get most DPS, and also does so ingame. The front mounted guns do not fire in this case, which can be easily be observed.
Maybe it again boils down to abilities. Someone already mentioned the Kortul Devastator's fast fire, the nanocrap of the Egg is not bad either and effectively adds to damage, but this leaves the Skirantra Carrier and the Antorak Marauder in the dust.
