Top 3 things you would like changed, fixed or added?

1. Duel spec (or even better Trip Spec)
2. Overhaul of legacy rewards: more reasonable prices (or no prices just legacy level), perks for high legacy levels, even more perks overall, more perks that apply to overall legacy and less 'character perks'
3. Off-rails space missions.

1) improve grouping with lower levels; namely implement a sort of "master and apprentice" mode that allows you to group with a low level player and help them through all their quests, not just their repeatable quests. Don't "remove" high level abilities but instead implement a feature that will scale the power of the abilities to be 5-10 levels above the current quest's recommended level (allow it to be toggled on/off on a 15 or 30 minute timer so if necessary the high level can bail their low level party out).

2) alter crafting so failed reverse engineering attempts gradually improve changes of learning a new schematic.

3) flexibility in weapons based on role + weapon training. For example allow all Jedi DPS classes to have the option of single saber, double blades saber, or dual sabers. Let all Smuggler DPS classes have the option of dual wield etc. It is kind of annoying that my Jedi Shadow has training in other weapons besides double bladed sabers but has to use double bladed sabers if I want to use some high level abilities.

All Orange or Purple items bind to Legacy

All Armor Adaptive

1. Better "Space" -- 3D, Ship Decoration, Pilotable, Multiplayer Co-Op in ships and turrets
2. Better Crafting UI -- Hierarchy Grouping, Mouseover item name on left side of screen to show item stats
3. In-game Voice Chat -- Without it meeting/playing with new people is short, curt, and difficult to know them. Vent. etc. is fine for existing guildies, terrible for meeting future ones.

1. cross server mail and legacy
2. more companion interaction, even after finishing the companion quests--and not just the romanceable ones
3. Did I mention cross server mail and legacy?

1. Space upgraded with no rails. (ex: Jump To Lightspeed)

2. Legacy Cargo Hold. (Have a Legacy perk to access a cargo hold to all your toons to store crafting materials etc.)

3. Instead of having voice overs based on class, update it based on species. Granted I know this is more time consuming and costly. Yet playing the same class with a different species that sounds exactly the same is kind of weird. (That way when you do release new playable species it's like adding a different play through, instead of listening to the same voice as before.)

You can do this already:

On PvE servers only. On PvP servers, the obvious possibilities for abuse are obvious.

I'd like the legacy to work in between certain servers. There are too many things that I want to do to contain within 8 characters. :P

Also, I'm sure it's already been said, I'd LOVE to see more armors. I think more headgear should be able to be equipped without interfering with the hoods on certain body armors.

As for an add, perhaps a style-based outfit system? Something like what DCUO does? Like if you find a better helmet but the one you have looks cooler, you can wear the better helmet but make it look like the cooler one is on?

Oh yeah, and maybe some ship skins? Like, laser-scoring, damaged or exposed circuitry, or different colors?

I dunno, just a thought.
