I changed my vote from Vic only to Vic for 2-3 weeks.
I think having the whole server on one continent for a time has a lot of value. The fact that you could always find people in the community easily (no boat ride / muling necessary) was pretty nice. More likely to run into people, to chill in Henesys, KC, even Perion.. I'd lean towards 3 or even 4 weeks tbh. I did change my vote though, because keeping up the momentum (realeasing new content, not having Ludi too far away) is probably important overall, for server health and player satisfaction.
