I think (and I think a lot of people agree with me) that it would be great to have more bays in the Legacy Cargo storage. As it stands five just isn't enough, not even if you're just crafting. And for players like me, who want central crafting PLUS a place to put gifts, XP buffs, and Legacy wide gear, five bays doesn't cover everything we need.
I would love to see the number of maximum legacy bays go up to 10, as that would give me space for all my crafting plus gifts, buffs and gear.
