I would think the new libram would have a low priority. Only stacks 3 times with 73 dodge for each stack. 12 seconds to get the full effect. Plus it only gives about 19 more dodge than the current libram. I don't see this glaring at me as a must have.
edit: and if the effect wears off during that 15 seconds, you have to spend another 12 seconds at least to get the full benefit again.
