In the Nefarian encounter within Blackwing Lair, one aspect of the fight is class calls. For hunters, this call will instantly break your ranged weapon rendering it useless until repaired. This simple addon does one thing - it adds the /unequipranged command that can be used with a macro and keybound to remove your ranged weapon. For instance, you could macro this like so:
/unequipranged
/equip [mod:shift] Rhok'delar, Longbow of the Ancient Keepers
