This is what i don't understand
" Sha-Touched Weapons will not be available in the new Raid tier but will still be available from previous Raids. "
" Eye of the Black Prince will be able to be used on new Epic Weapons "
" Eye of the Black Prince --- Add a prismatic socket to a Sha-Touched weapon.
So if sha touched weapons will not be available in 5.2 , and eye of the black prince only works on sha touched weapons , who came up with an idea that it will be useable on the new weapons that are coming in 5.2?
