Here is my feedback:
I am annoyed that some people got to complete “one-time” events more than once, and with multiple characters, when I could not even participate in ANY of them. I had especially wanted to fight the final boss. Forget the chest, I wanted to fight. But to my disappointment, I did not have that opportunity, even though I was logged on before the event supposedly was to have ended, and tried every reasonable way to find/trigger the event during that time.
So, that being said, I add my disappointment in with the other thousands of players who feel cheated and angry.
