I think they adjusted xp during the patch last night. Before the patch, Kaylee was a Lt 4 and needed 894 points to make Lt 5. After the patch, she was Lt 5 and only needed 495 points to make Lt 6. Took her through Stop the Signal and got enough points that she's just shy of Lt 8.
Upgraded weapons and consoles and dove into one of the Deepspace Encounters with the Klingons to test it out. There was two other Lts already there. Blew away a few Klingons and a VA appeared in a Dreadnought Cruiser. He preceded to scarf every loot drop. His ship was faster than ours so he zipped back and forth as the Lt's engaged the Klingons. What a loser... I mean I accomplished my goal of testing the ship, but it would have been nice to pick up a weapons battery or something. It was mildly irrating for me and I'm sure it was extremely frustrating for the new players.
Too bad that we don't have a button for Kick this jackass out of my instance.
