I just thought to myself: People like to call it Lagbar because, in all honesty, it's a pretty big resource consumer.
So then my extremely bored self though "Hey self, what would happen if they offloaded the entire Mabar event to a completely different server? Maybe even, by doing this, allow us to play with other people from other servers on this one special "Event Server" that we can access in game. That way, it doesn't drain on the normal servers and I can also play with people whom I've only heard about.
Imagine (if all of them still played) a party with Shade, Rogann, Cetuss, Shataan, Symmerith, etc etc all running around trash talking and killing the spectral dragon when it pops.
This would also have the benefit that if everyone was on the same server doing it, the dragon would pop up at least every hour regardless of the time of night.
Yes I understand this would be an absolute nightmare to code, and would never happen. I also understand that a lot of you believe Turbine is completely inept at absolutely everything and can't even tie their own shoes. I'm just throwing this idea out there for the fun of it.
