What I would like to see is that the Console/PC versions of the hotbars get saved via the server. This would save a lot of hassle for those on the PC and PS4/PS3 and when I say this it means a lot. In making it server side we wouldn't have to modify a lot of things like Ui/hotbars and all sorts of settings that are required when we start anew on either systems.
This would be great for convenience with the consumers.
