I have five wow folders all symlinked off the one main folder.

Works well until you need to patch. Then it can be a pain in the arse.

Easiest way to do it, is to Patch the main folder, copy it, delete the data, WTF, etc folders and paste yourself four clean wow folders.

Copy the WTF & WDB folders from your drone accounts and paste them into each folder. Then symlink the data folder from the main into each drone folder. Personally, I symlink the interface folder also, I just think its cleaner.

This does work well. My loading times are very, very quick.

I like it just because its clean as....
