Killing the Horde PvP gear vendors in Townlong Steppes

[Arethea]

It's starting to get really annoying now that alliance is killing our (horde) PvP gear vendors in Townlong Steppes. It's the only vendors we can buy gear from and some warlocks are using Rain of Fire to kill everything in the room in less than 5 seconds. The alliance vendors are friendly for us horde, so we can't attack them, yet alliance can kill our vendors. These vendors shouldn't be attackable at all, or you have to spawn other vendors in Orgrimmar, because this is starting to get really frustrating not able to buy gear.

due to rain of fire hack they kill everything in 5 sec.hits more than 5-6 times in 1 sec rain of fire must be fixed
