Not only that, why are you not guiding your girlfriend around her class? You say that she hit 110 in a month, which, for a new player, is INSANELY quick. Of course she's not going to know how to play her class well and of course other people at 110 are going to expect her to know the basics of her class.If your girlfriend "cried" after being in a chat room in a game then she needs to learn not to take internet avatars so seriously. How do you get "screamed" at in chat? What, were the big bad players using all caps? She should have used that as a learning experience instead of taking it as a personal blow to her self esteem. Now she knows to take taunt off from her pet. And by the way, its extremely annoying as a tank to have some idiot in the group with their pet taunt on, and more often than not, its someone trolling, which is why she probably got "screamed" at.
You're getting upset that people are getting upset at someone who has no idea how to play their class.
You did this, not them. Teach your girlfriend how to play the game first. WoW isn't about blasting to 110 and getting carried.
