This has probably been brought up already, but either way it merits retelling.
Killing ANY mob other than what you've already been killing will KILL your progress on exp/chests.
Just got out of the worst run i have had and just as we're hitting 5 guess chests and decent exp someone either pulled or aggroed a glowing mob and on top of killing a bunch of people with its aoe moves it killed our exp/cruor. Straight back to 80xp a kill and 2 guess chests
Also if you're leading a run be sure to express just how important it is for people to kill quickly. Its real important if people actually know how to switch between mobs as the one they're fighting dies. Or at the very least aren't the kind of people who engage a mob and then go do something else. Hard to keep kills rolling in when after a kill or a moved mob half the alliance is still standing in the same spot.
Also if you're in a pickup try and stress a bit of group unity. After that glowing mob we had some deaths and some people were almost at each others throats, which is good neither for morale or your kill speed. I actually had to make an example of a leech who decided it was fine to afk for long periods without even warning anyone. His party booted him once to stop him from just leeching and when he got back into the alliance and did it again he decided telling me to "f**k off" was the best was to respond when i tried to get his attention. The cor we replaced him with was a whole lot nicer.
