to kill the sandworm on our server?

What kind of question is that? ._ .
And even if they knew why would they share it out.

you're not supposed to actually kill the Sandworm, as your title indicates you did...if you did then you shouldn't be proud due to the fact you're obviously doin it wrong.

A lot of groups went after the sandworm when the expansion first came out, before it started using doomvoid. A friend and I have both killed it before. Though I seriously doubt either of us were in the group that was the "first on our server"

I was assuming he meant killed it when it first actually began to matter; because killing it any time before that really didn't matter and yielded no reward. Plus since it's been around for such a while I don't think there's any legitimate way to tell.

I know a few people that went out and killed it before the sandworms gained Doomvoid. As far as I heard, it took a lot of raising and kiting, and I was pretty impressed to see people with the title. It just goes to show that some people will go out and do things just for the fun or sake of it even if there isn't a prize at the end.
