I've been playing for a little over a month. I have unlocked 1 raid, by accident, which I will never do. I will not raid, specifically because of the toxic mindset I have encountered in the past on it. I'm not the best player, I know this, and so I am not going to put myself in that situation. I know my rotations, know how to keep my defenses up, and I know how to avoid giant glowing warnings on the ground.

In casual leveling I have had ONE bad experience.

A friend of mine talked me into doing a dungeon I had never done before. They are way more experienced than me. They were telling me over voice, "Pull everything! Pull everything! That's how you tank!"

Meanwhile I'm trying to maneuver around an unfamiliar area with huge drops. I fell off of a ledge. This caused a party wipe.

This was the dialogue:
Rude Player: "The tank didn't f"in tank!"
Froend: "They fell off."
Me: "Sorry! I told y'all it was my first time here."
Rude player: "That's no excuse learn 2 play."
Me: "I've only been playing for a week."
Rude player: "Don't play tank."
Friend: "It was one death, you've spent more time yelling at her than it took to get back here."
Rude player: "This ???? wouldn't fly in WoW."

We vote kicked him.

So is it all WoW refugees, or just WoW refugees? No. Though I do believe a good amount of it is coming from WoW.
