Guild Wars 2

Hello everyone, I have a question regarding the carapace leg armor, namely about how to obtain it. I’ve been Googling and asking around, and I seem to get conflicting answers (and it doesn’t help that the wiki is on the fritz). Here are my questions:

1. Is the only way to get the carapace leg armor by playing through LWS2? Does it not drop at all through the Silverwastes?

2. If this is the case (like most people are saying) how did I end up with with the heavy carapace legs (the wrong weight, unfortunately) in my wardrobe, despite having never even done LWS2 before?

3. Does the carapace armor box rewarded in the Silverwastes PVP reward track give pants?

Thanks in advance.

No but then yes. It used to only give the glove but the June 14 patch change it to allow choosing any piece.
