So summed up, the Gods put the humans on Tyria, expecting them to do great things for the world, but when the humans kittened up and took Ascalon from the charr, they said kitten it, gave them magic to make it interesting, then grabbed the popcorn and enjoyed the show.

Except they took the magic away, due to King Doric’s petition. They wanted to gift magic not just to humans but to all the races of the world. It almost led to humanties destruction and that gift did lead to a war amongst the gods themselves.

They left, as I understand it, because their presence and interference caused more harm than good.
