Sync across multiple computers
TSM already has the backup system.
It would however be great if this was to be extended into a real sync system for premium users.
The reason for this is that some of us (like me) use multiple computers (in my case a Windows desktop pc and a macbook) to auctioneer.
It's really annoying to have to wait for a backup to be created and then restore that backup on the other computer you wish to continue playing on.
EDIT: workarounds like sharing the files through a drive in the cloud shouldn't be needed.
But sharing the files through a drive in the cloud allows you to share everything: Addons, Account and Schreenshots. I am using a desktop and a laptop as well and prefer to share everything via Dropbox. Dropbox keeps 40 (?) versions of a file as well, so you can rollback easiely in case of desaster. IMHO sharing the TSM files only makes no sense to me. Hint: with "mklink /J" you can link folders from your cloud drive to your game's folder directly, so you don't have to copy between your cloud drive and your WoW folder manualy!
