As many of you know, in WoTLK beta Feral Cats are regenerating Energy no matter what form they are in. Jimmythenumbers said that this was "unintentional" due to the removal of Powershifting. They made it where you regenerated energy in forms, but then made Furor into a 40 energy cap for it with no energy restoration. This killed powershifting and made energy regen mechanics the same they were before.
However, Jimmythenumbers made another post:
What does this mean for Ferals?Originally Posted by Jimmythenumbers
Well, it's the greatest buff to shifting synergy since the beginning of Ferals. This will effectively allow us to Off-Tank and come out at 100 energy to deal damage, and it will allow us to come out and use our Battle Rez/Tranquility/Innervate and regenerate or start at 100 energy when we shift back in.
This means so much to Feral Druids and is quite possibly the greatest thing they've done for the Feral spec in a very long time.
However, even though this is great news -- We still cannot ignore the fact that our DPS scalability is still very poor & that we no longer have Int on our gear to shift + access utility heals/CC. Hopefully these things will be addressed later, but for now, let us enjoy this most awesome Feral love.
