Are you planning on putting in dissimilar factory adjacency bonuses?
I've previously mentioned (via discord):
1) How underwhelming minelaying is for the cost of a minelaying setup.
2) How almost all competitive ships are single offensive system (with maybe EBs and flaks squeezed into walls); i.e. almost all cannons, or all lasers, or all missiles, or pure beam, or pure rails
Adding dissimilar factory adjacency bonuses would not only make minelaying less underwhelming, but also make mixed-main battery ships more competitive than they are now.
