in 2017 1 os shields are charsi. either a 3 os magic option is better 100% of the time because your build needs the extra socket or you give up one mod on this shield and buy a 2 os one.
As this has ED, and ED isn't needed on a kite base just removing that gives u a 2 os shield potentially, and there are hundreds if not thousands of 2 os shields on every realm.
