Since name duplicates exist across multiple servers, the guild is likely tied to the original server, regardless of realm/faction GM leadership change. (original server meaning where the guild currently resides once the pre-patch goes live)
The guild name change is still for sale.
So it could also be possible that cross realm/faction guilds are going to work because essentially it will create 1 big mega server through phasing/sharding.
However if that is the case, then the question is where does one get anchored to, their own server, or the guild’s server. Or are the guild name changes still for sale because they will force duplicate named guilds to pick a new name once pre-patch is live?
It would really be nice is a blue could share some insight on this.
Or if community council could help get some answers.
