This is an idea I raised in a different thread, and I felt like posting it here.
Since Shae Vizla and Nico Okarr, previous sub rewards, were given out back in April, some players were left with no sub rewards at all. If they plan on doing this again, one thing BW can do is implement a system where players can choose between an old sub reward, or a new one.
However, I would like to point out another idea that was posted on Reddit not long ago by the time I'm writing this: Alternatively, implement a loyalty system which continues from where the individual players left off. OR: add previous sub rewards to the Cartel Market, as it has enough stuff in it that can easily give out filler rewards when there's nothing special.
Also made a strawpoll for it: https://www.strawpoll.me/15823798
