Tier 4: Soul of the Force of Nature Incarnate
This tier is both the most interesting tier and the least interesting tier in the list. It's the most interesting, because, well, this one directly affects your DPS, unlike all those other "silly" healing talents. Unfortunately, that also makes it the least interesting, because that means theorycrafters will just figure out what works the best, and everybody picks that one. The best-case scenario is that all the talents end up reasonably balanced, so I'm going to approach this discussion with that in mind.
First up is Soul of the Forest, which is a fairly bland passive talent. For easily distracted people like me, though, passive is good. Passive means "I don't have to do anything special to get a DPS increase out of this thing." Joking aside, it'll probably end up (once the balancing is complete) as narrowly the highest-DPS talent for feral and balance, but only if you get to stay attacking the boss 100% of the time. Any off-DPS time starts to cut into its value significantly.
