I can confirm that this is -still- working. Clicking off the imbue and re-imbueing both weapons causes my stats to change during each imbue. I even took off the offhand weapon and my health went down. Since your health is provided by the server and not the client (don't get me started on the GCD hack during the 3.3.5 patch), I can say without a doubt this works. The people saying it doesn't work simply are retarded and don't know what changes in stats to look for or they are executing the glitch wrong.
