As many of you know the Thunderheart Harness :
(2) Set: Reduces the energy cost of your Mangle ability in Cat Form by 5 and increases the threat generated by your Mangle ability in Bear Form by 15%.
When Wotlk arrives will it be wise to go back and get the 2 piece bonus for cat DPS?
Or do you think the stats on new gear will make up for the 5 energy saved?
