You're welcome!

Sounds like the gear damage icon to me. When that appears it basically means that your gear is severely messed up and you need to go to a vendor or medical droid NPC, click the bottom tab titled "repair" and fix it. Can be quite costly if you don't keep it up. Assuming that's what your problem is...

Honestly, I don't know where all this hostility directed towards new players comes from. I've seen it everywhere and it's always baffling because we were all new at some point. Don't let them get you down, for every douche in the game there are plenty more friendlies around. Just explain when venturing somewhere new (like flashpoints) that you haven't done it before and to explain the boss fights if they can so you know what to do. Welcome to SWTOR! <3

The Esseles Sentinel chest piece is very similar. But I think the Peacekeeper set from Synth is the closest match, or perhaps Knight’s Crusade by Synth's also. Those are both Heavy, but there are some that look very similar by Synth for medium too if you need that (Blade Master and Sentinel). And as far as I know, the Jedi Battle Expulsor Chest is still BOP from the Gree questline. Hope that helps.

Don't panic! The timer should just be when you can trade the item to another player or put it up for sale on the GTN. It won't disappear or anything.

Most of them explain what you get and what the actual limitations are. The only one I noticed that doesn't have a further explanation is the character creation choices. So I'm a little confused on what you want further explained...?

Errm, you mean like this? If you scroll down a little there is a side by side comparison. http://www.swtor.com/free/features

Not sure if this has been asked yet, but will there be any way to move items to a different server? Like, for example, say I want a color crystal from a cartel bag on Red Eclipse. But I open the box on Harbinger...would there be any way to transfer the item over to the server I want it on? Or do I have to buy separate packs for both servers and just cross my fingers and wish on a lucky star that I get it on the server I want it on instead of the server I don't? Hope that makes sense...
