Kaltra - Vengeance DH Illidan
I don't know about others but I do know that in my guild I'm usually in top 3 dps (with 580ilvl and most are 585 or higher) and I use almost 90% of my fury just spamming touch of chaos. Maybe a few soul fires for 2pc proc but it's better to get that buff while not in DF. Spamming touch of chaos in DF gives you CW procs that give a huge boost to your dmg + it's instant.
