13 years late, but I'm here.

So after 13 years of wanting WOW, but being addicted to consoles and not very good with PC gaming, I decided to buy the game.A little late, I know.I'm not new to MMOs, and I've watched a ton of WOW content on YouTube, etc.... but my question is: is there something that you wish you had known when you first started, that you know now, that might not be in one of these WOW Beginner videos?Thanks. Anxious to get the install done.
