Broke out thorn yesterday its much better but the re-load time is still an issue for me to recommend it over Fatebringer. If I'm not in the raid and can wear my Soujourn Grips for the buff to hand cannon reload speed along with Chain of Woe then Thorn rocks but when I'm raiding I have to drop my reload speed buff to put on my level 30 armour set. Its much improved but i wouldn't call it a massive upgrade since it can't be used to do the raid (It can but its not the best option)
