is the best pvp build i can think of; natures grasp is now castable in bear/cat forms as well, making it incredible against warriors and rogues. Natural shapeshifter is also a must, as you will most likely be shifting often to get out of snares. Thick hide isn't really essential pvp-wise - if you don't go for it, nurturing instinct is very nice (the set alone has 121 str, and 85 dmg/heal. This makes the 6sec buff give a total 297 extra healing, or a passive 143ish come the expansion).

Improved leader of the pack is not realyl a pvp talent; it will help in longer fights against paladins and warriors, but doesnt match up to fear/stun resist or an extra 15% dmg to crits.

This is an alternative, healing oriented build: https://vanillawowdb.com/?talent=MZxMGsbbZVxIzcq0Lo https://vanillawowdb.com/?talent=MZxMGsbbZVxIzcq0Lo

basically a variation on the old 30/21 build; you lose HotW for much more powerful heals. Your armour in bear should be respectable and you gain feral charge (sweet) also. In cat form your damage will primarily come from shredding, with boosts from naturalist and omen of clarity.

The whole set is rather expensive, if you dont want to grind for all of it then id take the chest, boots and leggings, for the 3-piece bonus. The rest of the set is more easily replaceable than these.
