I would like to suggest not to give ( 4 days ) maintenance before the Official Server Launch. Why?
Four reasons why I don't want a Maintenance after OBT :
1. First, people will be frustrated because that day is weekends ( some people have work on weekdays, that's the only day/time they can play ).
2. That is Long Weekends which means its 3 days off for some people.
3. No Ragnarok No Life for others ( Including me ROFL )
4. Last but not the least you MIGHT lose tons of players in this server. ( I love Sarah Server LEGIT classic and fun to play ).
I know it is hard to fix the server bug issues without a certain amount of time but I am just concern like other people including my friends/guildmates in this kind of matter.
We and other players already invest a lot of time/money since the opening day until now so I would like to suggest not to do Four ( 4 days ) Maintenance.
Although if there is no other option fixing the error/bug issues well I think there is nothing we players can do about it.
Thank you peace y'all!
