Design an event that makes is plausible to run repeatedly over a space of a day or two. Sorry but 6:30am on a Monday != good. Have to get ready for work/kids for school and somehow jam in a few hrs of gaming in between is impossible.
Found out about the overflow events still running, so I popped home mid afternoon to do one. 2.5ish hrs into the final event and the servers crashed.
Not impressed.
Yes I’ve seen the official reply saying that the time when AN runs events is peak population time (US) or somesuch but thatt still screws thousands of players worldwide.
