It's short. I'll copy and paste it right here:
When I first started, I was kinda befuddled for a bit on the leveling since the game was so much different than what I was used to. However, recently my wife has let my 5 year old son play it about 30 minutes a day, and after watching him, my wife told me that it was absolutely fascinating how he played and she (my wife :P) can't explain how he levels so quickly. She (my wife :P) encouraged me to play together with him, since in a very short amount of play time he has reached level 12. So last night I took my Necro over and we played together. He was very excited to teach me his tips and tricks to success in GW2, so I thought I would share.
Here is what I learned.
Apparently, you must wander in what ever direction kind of looks interesting to you.
A. If he sees another player, he may get very excited and run toward them to "help them out".
B. If he's surrounded by mobs, he will carefully look around and decide which mob he likes to kill exclaiming "Ooo he's level 11! I'm just 10! He could kill me!"
C. A lot of his focus is going to "win the diamonds" (discovering the waypoints).
D. If he sees a body of water, he might exclaim "Let's go have a swim! Follow me, I'll show you how to swim!"
When downed, wait patiently even if no one is around, because someone will eventually come along and rez you.
A. We've explained to him he can come back at the waypoints, but he remarks "I know! But watch! Someone will come save me! I promise!" and then proceeds to look around and wait patiently for as long as it takes. Luckily during our run, I was there and could "get his back".
B. When getting rezzed by two or more people, he gets so excited apparently that he leaves the game immediately to go throughout the house to tell everyone the exciting news. Of course, I exclaimed "Aren't you in a battle?! You just left them?!" to which he responded "Oh yeah!!!" and ran back.
He finds Youtube unnecessary when discovering challenging undiscovered vistas. His preferred method of technique is simply to wait patiently for as long as it takes for someone else to come discover the vista. He then watches them closely and follows them to discover the vista.
The most perplexing mystery of all, is the evening I spent with him playing, I didn't really feel like I was doing much of anything. It was a strange sort of relaxed just look around and enjoy your surroundings sort of play. However, he leveled up twice during our playing that evening. TWICE, without any of my normal "Ok what heart do I go to next? Any events in the area? How's my gear doing? Where should I put these points?" type play.
Anyways, I thought it was interesting...
