I am considering dropping a point in Icy Talons (loose 4% attack speed), to get the Goul frenzy ability. It looks like the cd is less than the up time, so since I have the gcd available in my rotation, the up time for the 25% hast on the goul would be close to 100%. Currently i get around 12.5% of my dps from my goul. My melee attack typicaly counts for 24% of my dps.
I am just wondering what other unholy dk's think of this and what factors I may be overlooking since to me it looks like the change would be a big increase in dps.
It's already been extensivly tested and Ghoul Frenzy just isn't worth the talent point. The only time it was even worth considering even a tiny bit was if you had trouble keeping your ghoul alive, but since they changed it so pets take near no damage from AoE that isnt a problem anymore.
Further review of this on my part provided the obvious answer, I didn't notice that it had a rune cost of 1 unholy. Given that information, yea its not worth it.
