I would humbly suggest that you make the Cartel Market Certificates "Bind to Legacy" rather than simply "Bound" to the character that happens to open the Cartel Pack. This way you don't penalize your most loyal customers simply because they open a cartel pack on one character instead of another.
I have many different characters and STORAGE IS A HUGE ISSUE. I have already purchased 5 account-wide Cargo Bays (PLEASE ADD MORE!) and my inventory is full on most of my characters. Apparently I am a Virtual Hoarder ...
Anyway, I would like to be able to pool my Cartel Market Certificates. After all, reputation with The Contraband Resale Corporation is supposed to reward your most loyal players.
Thank you for your attention to this matter.
