If you drop empowered Rejuvenation you loose a lot of healpower (especially if u use Rejuve/Regrowth alot - which your spec seems to propose)
So either drop your last tier of feral talents but 1 and reconfigure the resto talents (you won't need 15% more spirit) - if u need more mana take ILotP.
I really liked to play with 3/3 points in Infected wounds - made kiting warriors dk's and the like even easier.
Either way - Restoferal has huge utility but low heal/dps power - so it is not that easy to play.
