Not only should they stop wanderers from joining the fates (and some of those are really annoying with shouting in chat that people should spam skills in the hope of a server crash..) but they should have done the whole thing differently. Everyone that has participated in the stage to get there should then be able to go into a new instance (through a NPC that is open for maybe 24 hours after the task was complete) and then complete some kind of interesting solo fate. This way everyone that took part in this can get something out of it and not miss out because they need to do something important like having a rl, going to work or sleeping..(And yes the fate is nothing special but its also part of the content for this so people should be able to take part in it if they want to do that)
