I got this D3 on day one and had a blast playing it solo, then I played it with friends. I even didn't mind the hours of replaying an area with a friend coz it was a lot of fun
Then after some random patch, I wasn't really having fun...actually the game became quite a pain. So I logged on to the general chat room and asked wtf happened....apparently repair costs went through the roof and IAS was uber nerfed
stuck around for a few weeks, even visited their forums and did all the "like" bullshit to support a feature people wanted, but it just was never the same.
