Discussion and questions on the legacy purchases with cartel coins.

My main question is concerning the legacy wide (account wide) unlocks that can be made with cartel coins.

I was looking at the options to buy inventory slots with cartel coins and they have account wide options. If not all the characters on your legacy are on the same "tier" of inventory... how does that work?

Does it just unlock the "next" tier for them?

Or could it unlock everything previous up to that the highest tier that was purchased account wide?

Same goes for cargo bays. Does it unlock everything previous or just the "next" bay.
