If we can change the size of the build area from not being a cube it will allow for more designs. Right now to get the most of the build area for pvp we are kinda forced to make cube like ships.
If we get the option have a set ammount of m3 per core and set our own shape. Might solve some issues.
Also i kinda agree with gun restrictions but maybe have some leanancy, say maybe M cores can use upto L weapons, S cores can use upto M and XS and use upto S.
