CursedPh4nt0m Finally did some testing, and I was able to beat your wall with my own wall (Only did one battle though, maybe it was a fluke. Will update shortly):

Still haven't tested your design against my triangle, though it I expect it do at least decently, since my triangle was able to beat this particular wall design a few times (not consistently though... It depended on how the A.I. prioritized targets during a given battle).
EDIT:
Did another battle against my wall, same results.
Aftermath:

EDIT 2:
Did a third fight for good measure. Things got interesting this time, as your wall managed to sever mine into two pieces at the beginning! Still, due to the placement of CRs (which I believe was advice I got from you in the first place 😉 ), the broken wall piece flew on as its own ship.
Aftermath:

I recognize that your design is a lot more versatile though, as it has flak, and a wider array of weapons. I think mine only won because it overpowered yours with sheer cannon spam.
EDIT 3:
Welp, my triangle lost. It did manage to do some decent damage, though:

Still, I'll see what I can do to improve it. Though I might just end up making a new design soon enough anyways!
