I'd rather have mangle apply the armor debuff automatically and keep FF the way it was. FF fulfilled a lot of needs for a bear, and these changes essentially ruin it.
FFF IS our ranged puller, taunt should never be used to pull. I have been against this change from the first time I saw it.
The way FF should work, is that on live it should have a rage cost, and have it be removed in Cata, which is the opposite of the way it is. (since on live it works as a range pull but is also being used every 6 seconds since it does so much threat). Having not really tested bear at all, I am told FF (bear) is doing about 2/3 the damage/threat it does on live. This creates 2 problems. 1) no bear will ever spec into feral aggression because we will only use FF as a range pull and not part of our standard rotation, regardless of FF's CD 2) our only ranged pull HAS A COST.
Armor should be moved to mangle, which would give give us a reason to use berserk at the start of a fight (to get the 3 stack up faster), furthermore a reason to even spec into it at all as bear which at the moment most bears will not. And it will also let you remove the rage cost from from FF, redesign feral aggression, and INCREASE to CD on FF (bear) to really fulfill the role of a ranged pull.
The big thing is, if the damage of FF really has been cut by that much, there is no reason blizzard cannot double or even triple the cooldown to solidify that it is indeed our ranged pull and not supposed to be part of our rotation.
