Hello - I have a couple of friends who have quit this past year, and this is going to be based off of what they told me so i am very sorry if I am not going to give 100% accurate reasons why.
Let's get started
1: Many people we're freaking out about how +11's were going to be a thing - they began thinking that the market would begin to being corrupt, and or make it more a of cash spending game.
2: People are upset with the change from Outspark to Gamigo. Mainly because people are not used to change and it's a whole new company taking care of an mmorpg. A slogan with some of my friends is *blames gamigo*, so yea gamigo.
Hope this was useful
