I've no problem with Vareesa's story, though she was ultimately a stand-in Alleria for Knaak's Rhonin story arc. They could have fleshed it out more if they wanted to but she's always been a supporting character, so I don't expect too much in that regard. What they've done with Alleria and this whole void story arc is bothersome though. The entire thing felt forced. They could have explored a darker path for her without turning her into Gollum. It is what it is at this point though. It's their story, I'm just a consumer, and I don't care enough about those characters to quit enjoying the larger narrative because they screwed up a sub-plot.
