Necronus of Midgard here to put in my 2 cents. Just as a intro, I'm the points keeper of the Dynamis LS "Delevel".
Anyway, my initial opinion is that Midgard might spell the death of your calendar. I'm not wishing the death of it upon you, its just my initial expectation. Midgard has had plenty of internal server drama in the past (non-BG worthy), and many people including members of my own shell are ... well ... kinda jaded? In addition I'd list the following thoughts as to why I made my conclusion:
A) I'm not sure how shells on Quetz are set up, but on Midgard, while there are a few standard "do everything" endgame shells, many of the other shells are single purpose. Thus many of the people in my Ventrilo server alone are in a tangled web if interrelated shells ... dyna shells, limbus shells, einherjar shells, etc. People often have 3-6 pearls each, and its rare that any two people have the exact same set. As such there is a VERY delicate balance of schedules so that any one person doesn't miss an event. One person holding up shell A's event can lead to having to abandon either Shell A mid event or skip/be late to shell B.
B) The jaded part I mentioned above. Just surveying people I know (which is technically a sampling of a dozen shells) all said simple "screw that". I realize its a small sample of people and the people I know by no means represent the server as a whole, but it was at least a small part of my conclusion, but I'll just glaze over this one and move on.
C) At first I was angry you guys weren't being absorbed into our server. But then I put on my 20/20 hindsight goggles and took a good look at how much our population is suffering. I thought to myself "Even if we did want to follow the calendar ... COULD WE?". The current answer is no, but with an asterisk. See, just looking at my Dyna shell and 2 of our "sister" shells in that tangled web of shells I mentioned, we all have attendance woes. My shell would put down 8PM Tuesday and 2PM Saturday as our times, but if you look at this past Saturday, we didn't enter until 3:30 PM. Kinda kills the idea of a calendar huh?
Often, shells like mine and several other I know will gather at the right time, but ocassionally spend 1-2 hours waiting for numbers to get better before entering or cancelling. Occasionally we'll even toss a tell to a sister shell for a joint run, or to call off one shells run and let individual people decide to "tag along" with the other shell.
So anyway, that was my logic as of right now. Obviously the merge can seriously alter the state of the above three points, especially A and C. There might not be a cure for B, but who knows.
