Jaina, at her core is a decent character. She was one of the best things in WC3 & Vanilla. You're just bitching because her character his human and it's cool to shit on humans in the game and Jaina in particular.
First, people complained because they made her too neutral and peaceful during Wrath. So they dropped a tactical nuke on Theramore and gave her a reason to begin distrusting the horde. And when she becomes very proactive against your precious fucking blood elves because of the whole Bell incident, everyone shits the bed and gets bent out of shape.
Now they are trying to undo all that and make her more relatable as a character, because she still has a place in the story and you don't want that either.
I truly dislike the way Golden writes a lot of characters, and I seriously don't like how they have handled Jaina, but the human bashing is getting to disproportionately stupid levels.
