Before you comment you might want to do basic research? less revenge casts is less defensives as you still need to cast ignore pain as well. If you check my other post I explain about how it is tied together. loss of damage Damage is also leech talents that are built into the prot warrior spec. The buff to Ip does not work out when you cast it half as often, so one cast at 600k with new buff it would be 780k and 3.5% max hp healing from Ind now compare it to 2 casts of Ip 1.2 mil and 7% of max hp healing from ind. The Ip buff is not even close to compensation for the nerfs. so if you want to say well it will be more like a loss of 1 of 3 casts the math would be 2 casts of new Ip 1.56 mil + 7% of max health vs 3 casts 1.8 million +10.5% of your health healed.
