I understand that realism isn't really a priority here, balance is.
That is ok.
But the mass change such that we no longer have any metallic honeycombs to work with purely for aesthetics without making our ships heavy as sin... I don't understand.
As DJ Slicer said, at least give us aluminium, an already popular honeycomb for non-pvp use, back down to the ~25 territory. Or better yet, give us a metallic honeycomb in the decorative category, with extremely low weight, but no PvP viability.
It's a pretty hefty hit to our ability to make fancy looking space ships, that look like space ships, and can still fly well.
Unless you really want all of our ships built entirely out of wood, marble, and concrete?
Don't get me wrong, I love that we have the *option* to use some of those fancier honeycombs purely for aesthetics now... But... Space ships should mostly be metal =D
