So I was thinking recently about what I'd really like to see in the game and came up with a few minor things that I'd like to toss out as suggestions.
A way to change the background lighting in the preview box in order to alter/eliminate some of the shadows that make it difficult to get a good view of what you're previewing. Either an automatic highlighting of the armor piece/weapon you're trying to preview or a button that says "Highlight previewed item." This is something I particularly want for when I'm trying to preview bracer drops because I have no idea where to look for them. I think they're located somewhere around the glove area, but I have no idea where so a highlighting feature would really come in handy for me.
I would also like more in the way of character customization. More hairstyles, more hair colors, more face options, piercings (ear, nose, etc.), so forth and so on. Basically, extra ways that I could make my character more specifically MINE. I think that this kind of thing really helps players form attachments to their characters and, therefore, to the game. Armor dyes have been mentioned by other people in other threads and I'll take the opportunity here to agree with them. The games I've spent the most time in over the years have been Ultima Online and CoH. One had armor dying tubs and the other just had mad, epic customization and the ability to independently color every part of what your character wore. Again, it helps players to get more attached to their characters if the characters look exactly the way we want them to look and the more attached we are to our characters, the more attached we are to the game.
Finally, and this is an I-might-be-the-only-person-in-the-game-who-wants-this kind of thing, I would like crafting schematics for different styles of lightsabers. Allow me, if you will, to explain. Right now, the only empty sabers an Artificer can create as he-or-she levels up the skill are the Custom Lightsaber and the Custom Double-Bladed Lightsaber. (Somewhere around max crafting level, you get the Elegant versions of those as well as some pre-loaded blades but it's a long way off after you get the basic Custom schematics.) As replacements for what you get on Tython or Korriban, they're not bad but, well, they're not all that good-looking. It occurs to me that, surely, at some point over the millennia there must have been Jedi or Sith that had an artistic flair which would have shone through when they designed their lightsabers. I would like to see schematic drops that reflect this. I would like my Sith to carry something that radiates menace and my Jedi to carry something with a certain swashbuckling panache. And I would like to be able to make them myself. I'm probably the only one weird enough to want something like this but, hey, I'll put it out there anyway.
