Raze,
  Thanks for the tip.  I have been doing this all along and probably have enough ISOS charms to make all my gear durablilty 500/500.  Just seems kind of futile to buy stuff that I know I will never use and never be able to cash back in unless I find an item that I might want to buy. It is dishartening to check a vendor's Inventory and find most of the charms are Durablility, Mana, or Intelligence since I am not playing a Mage this time through. 
  Keep up the good work, your posts are very informative.
