Perhaps it is just me, but I've never had beam weapons of any sort give full dps, whether it be spire ships or hbc. They hit one or two targets, and the rest is just wasted.
Perhaps a casualty of rarely playing "normal" (yet alone high) cap games.
If I micro them, I can maybe get 1/2 of their total dps.
So maybe modular forts excel on offense. Should have known. The best shields increase their health by 125%, but if you replace that with weapons you increase their max dps by 550%, so in practice you boost damage by at least 200% on average.
Again, in fallen spire, who cares? I get max lasers, shields, and hbcs by default. I guess I should be happy.
I pity the fool who does not, though.
On the other hand, you could with the same amount of research get MK III forts, who while putting you in debt forever would still be better in every way if you could afford it.
So are modular forts the poor man's fort? Not a bad alternative I suppose.
