Guild Wars 2

Zero Pips is still possible. I just got them yesterday when someone of my DCed/quit. It was the only time it happened to me, so maybe it is restricted to 4v5 scenarios.

1. I am on my Phone right now so i cant provide you with a guide, but i am sure there are some good ones out there. Google is your friend. I Know this always Sounds mean but my other points are more important for you anyway.

2. There is a Website called metabattle.com. They store the most common builds. You can copy them if you like or just use them as inspiration to create your own build

3. You cant Do anything wrong so dont worry. While leveling you will get enough hero points to max out all skills and specialisations (except Elite) even with out doing a Single hero challenge. So even if you feel like you did something wrong you will be able to undo it when you reach 80, so have fun and find your own playstyle

I hope this helped a little
