Blizz is demonstrating they learned nothing from the complaints regarding Kael'thas and Illidan in BC. People hated that they turned both into villains because they were interesting characters and it felt like we were losing them for no reason. People hate Lore'themar Theron because he is boring. Yet here we are, taking the most interesting faction leader and turning them into a villain and replacing her with a boring leader.
Here's a hint Blizz: create interesting characters and torture them for 300 pages. THAT is good writing. Deleting all your interesting characters by turning them into villains and killing them off or removing them and then replacing them with a bunch of boring characters SUCKS as storytelling.
