I am sure some, if not all, of these are repeats ... however, I don't have time to read all replies to the OP. I realize this will sound overly-critical, just keep in mind I am a rabidly enthusiastic fan of the game.
SGRAs. We haven't heard any updates since shortly after launch. Three words: Slave Boy Outfit! Just saying: Equal Opportunity and what-not. Legacy Bank to share items between all toons. Also, having to mail everything is costly (eventually) and time-consuming. Shared credits between all toons. Social and valor shared level: Levelling up social and valor takes a hot minute, and doing it for 8 toons is a pain. More Legacy unlocks for high-level (Legacy 35+). Legacy is shared, why can't we share social and valor? Companion color-matching. PLEASE. Quick Travel to ship. Too many credit sinks and time sinks: Lower costs of unlocks and item ripping, and can we have an option to skip orbital stations? The companion persistent weapon issue is highly annoying. Craftable PURPLE crystals of all levels. Since pre-launch, purple crystals were the "Inquisitor" color, yet it's impossible to get them until end-game and still difficult even then. NEXU PET. Just saying. I want an evil, spiked kitty. I mean, Alanna Solo has one in the Extended Universe. Please. More color combinations for armoring (all of the good clothing designers apparently work for the Empire) . More purple ... for instance ... on both factions. And some black/grey for the Republic would be nice, afterall Luke wore all black in Return of the Jedi. A way to preview weapon appearance. More character slots ... ASAP. I need a 12-step program for my altaholism. More variety of rewards for Live Events: yes, I'm referring to the 90% speeder. 90% ... Grey relics. My BH needs some that I can use.
