I mentioned the ability to learn how to learn earlier. I think that is a crucial skill for gamers (and certainly in general too) to pick up on. You can learn how to question yourself and your actions and learn from your mistakes. If you constantly do that then you will always have an edge against newcomers even if you are not a natural born genius (I don't believe in the existence of genius at all, but that i sa whole other topic).
I have learned so so much about the game I would have never imagined as a newbie once I started multi accounting. Just seeing how other characters work and how they interact with eachother teaches you to avoid a lot of mistakes and a new player simply cannot know about any of those synergies.
Nontheless at least this is an interesting discussion and not some name calling
