I will state some things I would like to see, these are likely already stated by others, but I think the more people pointing something out, the more likely it is to be considered.
1) GTN Search. I would like the ability to, if I want to find one, specific thing, to look for it. For example, I want a Yellow Saber on my Jedi Knight. I cannot just search for Yellow Critical Crystal..I have to go through all the mods on the market. This hurts both me(by making it harder to find what I want), but also the Crafters who are trying to sell such things on the GTN(by making it harder to find what they are selling).
2) Having the option to choose if your hoods are up or down. I put all that effort into tweaking my character's face, why do I, if I play a Jedi, have to always have the hood up?
3) More customization options in Chargen. I do like the Body Types, but would like to see something more like an "advanced chargen" option, where you can take all the options for a spot and use them, and have some sort of sliding scale for the body type for people who want to make even more fine tuned adjustments(like, female body type 4, but with a smaller bust-line, and slightly broader shoulders). Also, a colour wheel type setup for hair and eye colour for the races that have a huge range of said colours.
4) Ability to reskin the look of my ships. Maybe I am not a fan of the red on the Jedi ships, maybe I want different colours or maybe even marking son my Sith ships..These should, as much as anything else, represent the player's choices, even if they are just vanity items.
5) More colours of lightsaber crystals then just red, blue, green, yellow that are craftable. These should, of course, not be majorly easy to get, and should be something that feels like an achievement to get, but they should be available. Especially since this is before the Thought Bomb on Ruusan, and saber Crystals are supposed to be any colour of the rainbow.
6) Greatsabers for Sith Warrior: Juggernaut and Jedi Knight: Guardian Mechanically, make them a separate type of saber, but have them do more damage(they are wielded 2 handed, after all). I will admit: not having this option made me play Marauder and Sentinel.
7) Shoto for Sith Warrior: Marauder, and Jedi Knight: Sentinel. These would be an off-hand saber only, and would give a bonus to deflection and do slightly less damage, since they are a defensive-type saber.
