There’s a lack of love for the new Heart of the Wild talent, with Arielle also joining in saying how useless it is, compared to Displacer Beast. I look at it differently though, as I see the purpose behind the talent. Heart of the Wild is supposed to return to us the hybridness we used to have back in Vanilla but not making it overpoweredly so (like arguably the Cataclysm hybrid feral) by putting it on a (long) cooldown.
Personally I love this idea, and when Mists of Pandaria comes I will be looking for reasons to take it. Unfortunately at the moment the implementation is not done correct, and the talent isn’t really worth taking. Let’s look at the permutations, ignoring Balance <-> Feral switching since it makes little sense to switch from one DPS form to another.
Guardian -> DPS
We’ll get 150% Agility -> Intellect conversion for Wrath-spamming for 45 seconds. If our mana holds up, will that really do more DPS than going into cat form with 100% Agility using just Rake/Mangle/Ferocious Bite?
Restoration -> DPS
Again, would be interesting to theorycraft how Moonfire + Starfire/Wrath at zero mana cost would compare against Rake/Claw (Remember this skill?)/Ferocious Bite with 150% Intellect -> Agility conversion
Guardian / Feral -> Heal
This is actually plausible, with 150% Agility -> Intellect conversion. We’ll of course start off with Tranquility, then Rejuvenation/Healing Touch spam, but will our mana hold up?
Balance -> Heal
I’m not too familiar with the Eclipse mechanics and whether that would be sufficient to make up for not being in Restoration spec.
Feral / Balance / Restoration -> Tank
Will an additional 95% armor really be sufficient to tank with, given that Thick Hide gives Guardians 330% and we will be missing Survival Instinct, Survival of the Fittest and Savage Defense? Interestingly Restoration and Balance Druids are slightly slightly better off than Ferals because of the 150% Intellect -> Agility conversion.
At the moment I think -> Tank is not plausible. It is highly doubtful that we can tank anything except a weak add with simply a 95% armor boost. -> DPS is also lackluster with the lack of the skills that synergizes to give our DPS specs the DPS to match the other classes. ->Healing does seem plausible though, except for the mana issue.
Until there are some improvements to this talent, I would say Blizzard could simply describe the effects of this talent as “Increase the healing done by Tranquility by 50% if you are not Restoration spec”
