Yes.
The LFG tool isn't that good, it took it 45 minutes to find me one group, which then disbanded within ten seconds. And this is while the test server had a ton of people on it, too. And when we tried to rebuild the group, we got an "Invalid group duties" error, which apparently meant that none of us existed.
The new PvP quest automatically gives you 350,000 credits, so that's good.
The titles for participating in this test are really hard and confusing though, since Bioware did NOT do a good job of explaining the criteria.
Performance seems better...
But all Sith Assassins (like me) got a pretty major nerf...
EDIT: Oh, and after getting transferred from a live server to the test server, I learned why character transfers aren't publicly available yet. I ended up getting two of the same character, one with the right name, and one named AWDEREEDRSW.
