You might think im a j3rk after i say this.

We are a player that play in their server, we are the one who should follow their time. They have their own maintenance time and we should follow it. If you want to finish the event, then fini* before/after the maintenance, they already gave the maintenance schedule hours ago. Read when the maintenance would happen and make your own schedule so you could finish all event.

And some people might only able to play in specific time, it might be collide with server maintenance, but thats your own fault, if you cant play in other time, then why play in a server that collide with your schedule. If you want to keep play in the server even after that, then don't complain, since you are the one who decide to play, you should deal with their maintenance schedule.
