So you're comparing an unavoidable CC (HC) to blind / AoE fear and RoF?
1. You can easily Avoid the Aoe fear, it's not like a lock can "Shadow Grip" you into it.
2. Blind..not even going to discuss - it's more than fine.
3. RoF is avoidable aswell, making DF / RoF DR each other is fine too.
congrats on cataclysm giving you aj access
frost needs adjustments but this is the most retarded way to do it, blizzard is so dumb when it comes to balancing
hopefully unholy gets some love and gets some of the bugs and clunkiness fixed
