I've had this problem on occasion on PS3. My internet is not the best nor is my connection wired. I've gotten lion a few times as well, usually bee though. I've put it down to my internet for the majority, but given people with better connections get disconnects I figured I'd at least post. There's no better ISP in my area so I can't really help that anyway, and destiny has run better than most online games I've played. The fact that it played so smoothly during the beta was a big factor in me buying it at all. It's rare enough that it doesn't really bother me.
