Warlocks - Shardtracker / Servitude

[Ozymandias]

Quick question really:  Does anyone use Shardtracker or Servitude?
If so, would you recommend them?

I dont use either, but I know Feeron used shardtracker and said it was very good.  I may have a look at them at some point, as they are class specific to me.
