I suggest the removal of a number of "Free-to-Play" restrictions.
1) Allow ftp and preferred status players to receive help from customer service.
How are these players suppose to receive any sort of assistance when they are not able to ask for it via forums or even the in game support.
Example: http://www.swtor.com/community/showthread.php?t=680890
Due to a screw up anyone working on that mission had to restart the quest and search for the HK-51 parts all over again. If you're not a subscriber you're not going to receive any bit of help not even an acknowledgement. This is unacceptable.
2) Allow them the ability to mail credits to other characters on their legacy/account.
The inability to send credits through the mail is understandable when it comes to credit sellers, however that appears to be in the minority.
There are a number of people that would like the ability to send credits to their alts through the mail, otherwise they would have to sell something on the GTN and buy it back on another character just to transfer credits over.
Why would people like this; so they can purchase character specific perks.
3) Increase/remove the credit caps.
A number of the "hot" items on the GTN are above the credit cap for each status. Even escrow withdraws are, at times, over the credit cap.
An increase/removal of the cap will allow players to purchase more items and sellers will have a broader audience.
Those are the main suggestions I have. If I have any more I will post them
