Well, if we decided to make it all shaman, even if it's just like normal ToT to start with, we'd probably be able to get it on the front page of OpenRaid for more signups.
I'm not certain we could effectively "tank" SoO, even on flex, so I'd suggest just starting with ToT. If that goes well, we could certainly try SoO later.
Depending on how far you move it back it could be a problem for some people. I will be busy March 13-16, not sure how far you're thinking about pushing it back.
So, I just got an email saying the new date for this "Starts Wed Dec 31st 17:00 - 22:00". Double checking the actual site I see it's on Friday, March 14th 2014 at 18:30 (mountain). Silly email, wonder if I should contact Open Raid about that mix up. Sadly the time no longer works for me as I'll be traveling then. Hopefully I can still catch the steam of it.
It's just a tentative date right now, we will accommodate the best we can I just moved it from the 28th to give more time, discussion is welcome as always:-)
Regardless of what we do and when we do it, definitely looking forward to an all shaman (or even nearly so) event! Thanks for getting this all together, Lavalash : )
