I've been playing a couple different characters with my girlfriend, we made a couple of paladins, and these characters are growing further apart in level over the last few levels and I don't know why. With either rested, or normal xp, she gains less xp per kill than me. She thought it was because I was getting more kills, so I let her kill things and she still gets less xp. We tried our other characters that we paired up and they're in sync. Is anyone else noticing this issue?
