I noticed im getting a 0 for this enchant. While not as good as windwalker it does allow a tank to avoid ALOT of damage from Elemental mobs by chain silencing them. Furthermore, there are a LOT of elemental mobs this expansion.
I feel this enchant should be on par with mongoose, blood draining, and bladeward at an about 15. Or at the very least on par with a weapon chain at 14.
