Before house of wolves, I got burned out with all the grinding and quit for many months. When the taken King was released I decided to see what was different but this time I am going slow so I don't burn out as fast. My words of advice are simple. When you hit the wall and burn out, quit instead of complaining. Don't get me wrong, when issues come up we should address them but to just throw blame is not constructive and you should just leave because your burned out. Come back when you just want to have fun.
