Title pretty much says it all, right now Guilds can have members on any server but it’s completely pointless because the upgrades and influence are per server.
If not making them cross server atleast allow a way to transfer the guild’s upgrades from one server to another (Charge gems for this even if you want).
Our guild is transferring to a new server but we will be losing thousands if not hundreds of thousands of influence including dozens of 1-time use Tomes that our members got for Digital Deluxe.
