It's not very useful for your PUG, but Muscle Memory is great for mages or crafters that use INT. I'm currently getting GLA to 36 for Muscle Memory II for my CON. The ones that convert mental attributes to physical ones are correspondingly sold at both DoM guilds for marks (Will to Power, Driven by Faith, Complete Control).

Each reassign appears to take a fixed amount off each stat and refund the points for both stats and elements. I may be wrong on the fixed amount part. You can reset at lower physical levels frequently, like every 30 minutes. It scales up, and at level 50 it takes 3 or 4 hours before you can reassign again.
