Thanks for the great work! I'll definitely try this when I get back home tonight.
One thing though, wouldn't it be too much of a DPS loss to use festering right at the beginning with all the buffs, prepot and in most cases blood lust? I usually use the first few sets of Death runes to SS with all buffs and prepot then when all the buffs fade, ill go back with using festering with BFD to extend NP's duration.
