Now as you all know the resilience was buffed so this number isnt quite as outstanding as it would be if they had not buffed the resilience, nevertheless;
1411086-1015981.92=395104.08, or ~395k necro on a player.
I only tested for a few minutes, and this is the only one I was going to bother screenshotting, however I did get a 1512739 which translated into a 423566 or ~424k necro on a player. I'm sure it could go higher, but this is one of the lovely things I like about 5.4.
This is a standard "perfect" plague leech setup (haste mode engaged), with 12 stacks of blood tap, 4 available death runes. As you can see I didn't empower, and there was nothing to empower anyway unless I wanted to wait for the ff/bb and get another 4 necros in, which could be rather tasty too. I think I'll go do that now.
