Context for Frostfang CDR removal?

I'm not seeing any context for the removal of 10% CDR as well as what the plan for FCQ is as last patch, the build path was changed to Blasting Wand + Frostfang instead of Fiendish Codex + Frostfang. The way it is now on PBE, STE line is even worse off than it was before it got 10% CDR. Is it time to shelve this support item line in favor of something else because it can be abused by niche midlaners?
