@Astalion: How on God's green and verdant Earth did you manage to get 5.5k Obliterates while DW? Or 3.6k Frost Strikes for that matter?

Look at the huge differences between the average numbers here and the ones you show. I understand that Glyph of Disease isn't simulating as well as it should. But you really broke something or changed something. My numbers are way different than yours.
Edit: At last, I finally got a Frost Simulation over 7.2k.

Astalion's priority and switching Blood Strike glyph to Disease did the trick. Used dual FC by mistake in the first one.
