I won't disagree. However, the flavour of the class according to the recent quest appears to be degrading. The Sha appears to be a more spiritual approach of Darkness while Warlocks are depicted more like scoundrel mages instead of DARK mages. It could be just me, but I am disappointed.
By the way, the quest may have indeed been rejected because of laziness on their part similar to how only 20% or less of the questline remained. I was looking forward to see new Warlock lore but instead got a tiny scenario focusing on stopping a cliche boss and stealing valuables from a temple...for financial profit. Only to get green fire by juicing a small portion of another's power.
What I am trying to imply is that the questline may have been crippled and scrapped, but the general lore direction remains the same which is that not only Warlocks don't get Sha, they get a unique taste of rejection too.
