Solution to transfer between clients without hurting server load. Allow an export / import settings option that saves your settings/ui/macros etc to the server that can be imported on the other machine.

EDIT: read a few more posts and saw the backup thing in the launcher. I didn't even realize that was there. That's good, but I think it would be better to have this option in-game, save to the server and be usable on ps4/ps3/pc.
