If you're not quite sick of testing, it might be interesting to see how an "all front DPS" build using turrets and dual heavy cannons actually works.
I actually do want to test this. I'll be honest, part of the reason I have spent time testing this stuff was for my own information, so I can determine the trade-offs of a build. Currently I don't run with turrets on my tactical escort, because I like having better side and rear damage, and I don't think the added damage of the turrets would be that much. However, I would like to know for sure.
So, I will try to do some frontal damage tests by adding turrets, but it might be a week or two before I can get to it.
