I could be way off but I'd say a few mil. My guess is some would think the block is too low for what they want and the INT isn't really that great of a stat. I'm a firm believer in "One man's trash is another man's treasure." I'm sure you wouldn't have any problem selling it.
id think 1.5-2mil you can get a 20% SS with the 4% melee damage and 4% elites with resist all and str for like 5 mil so i think 2 mil is a good estimate
Thanks
