It was a good event but I think your post should be in the "how can gree make this game worse" thread.
I can't kill 100 bosses unless I'm using gold for most now. I need to be able to start when the event starts and not stop to wait for the various faction goal roll outs. Perhaps as soon as the first goal is reached the second goal could be rolled out so we're not sitting on our hands trying to play two events at the same time one where we are in a hurry to kill as fast as possible and a second where we are waiting.
We are a smaller faction and although we completed the last event if we have to all shuffle our lives we just won't bother trying at all.
