Warlocks need an ability to drop threat in SOD

It’s impossible for me to do old raids with tanks who are not as geared as I am. I can afk half the fight and the moment I get a shadow bolt crit, boss goes on me. The affliction tree has nothing that reduces threat and going into Naxx, it’s just going to get worse as our seals get stronger. Not to mention, affliction will be king again considering the tier set is made solely for affliction locks.
