And,
plague leech is not always a dps increase over unholy blight. If you use unholy blight with 2 x trinket proc + pillar + fallen crusader proc + (pot), and are aoeing, you can do up to and over 10-15k dps more aoe damage depending on how many mobs are up.
You can gain up to 4k more damage per tic of each disease with correct usage (10 second of frost fever up until your next howling blast, 30 full seconds for blood plague) . That is alot of dps per mob.
This is way more dps than plague leech could ever hope to achieve over the course of the fight.
Lots of cleaving + proper use of unholy blight, it is an easy winner.
