DC goes down to -7 levels post 76 now. I was still getting .3's past 81 caps on dolls in Sky on WAR doing trials/WSNM latent on GA--4-6 levels past their highest/lowest level. 5 is a good index to go by, which is usually what I go with for a quick reference. It's a bit better when your DC's are a little closer though, but -5 for the minimum pop level is a good start. If you aren't getting anything, then go to the next higher target so it's a bit closer.

That is one thing that baffles me...people will spend HOURS on one mob and then whine about not getting any skillups--you would think they would try a differnt mob, or at least strip off the ACC/ATT gears or something. If you strip naked and still get nothing--maybe it's time to change target.
