The Class Tree for Feral is relatively locked in. You have a few situational options to make in niche situations, such as if you happen to need Remove Corruption for a specific piece of content, you would need to drop 3 points from the bottom tier of the tree. Those can be personal Utility points such as Well-Honed Instincts + Mighty Bash / Incapacitating Roar, which you need to get to it, as well as a point in Renewal or Heart of the Wild. You may also find use in Maim in specific scenarios, realistically mostly Mythic+. In that case, you’ll have to drop one of the points listed above, with Renewal being the recommended option. Another option is to drop group/raid Utility instead of either personal Utility when making the aforementioned situational choices or, generally, to put more points in personal Utility Talents. Both group Utility talents are very strong when used appropriately though, so this is generally not recommended.
Innervate is a very impactful cooldown for healers, though sadly, it’s not currently usable in Cat Form. Nature’s Vigil’s value can be hard to gauge, but it’s best used on Cooldown and can effectively replace a healer for its duration in certain scenarios. The reason the Talent is so strong on Feral specifically is that most of our AoE Abilities function as single Target Abilities as far as Nature’s Vigil is concerned since they are bleeds.
The most significant talking point is that none of these trees take Survival Instincts, which might be extremely useful or even necessary for some Raid fights or higher Mythic+ keys. Unfortunately, it is quite expensive to get, and none of your options of things to drop for it are ideal. It might even be worth dropping some damage points from the Class Tree instead, such as Heart of the Wild, to pick up further defensives there, such as a point in Ursine Vigor, making the lack of a very impactful defensive less noticeable. In the case highlighted above, you would simply go into Bear Form every time you would otherwise press Survival Instincts.
