Since you want to do M+ content only here is my advice to you.
As a general word of advice check the wowhead and IcyVeins guides, join the Dreamgrove discord server, this is the druid discord with hundreds of druids discussing all specs and roles.
For talents the build I run is:
- Brambles
-
Ursol’s Vortex, when I want an extra kiting tool, especially on Necrotic weeks. Else I go with Wild Charge.
- Restoration Affinity
- Typhoon
- Galactic Guardian
- Earthwarden
- Rend and Tear
Stat priority is:
ilvl > Versa > Haste > Mastery > Crit
Haste and Versa are your main stats for M+ run if you run the Earthwarden talent. Since Haste lowers the cd on Thrash making you squeeze out more stacks. It also lowers the cd of Enraged Regeneration .
Versa is superior to Mastery so it is always advisable to pick it.
For Azerite Traits:
The general consensus is that you should always stack 3x Twisted Claws,
1x Layered Mane is good especially on Fortified weeks,
Wild Fleshrending is a good pick for increasing your damage and aggro so picking 1 and rarely 2 is ok.
Personally nowadays I experiment with Power of the Moon a Balance trait as a damage boost trait, but that’s just me messing around.
Stay away from Gory Regeneration, it is one of the less value for the buck traits we’ve got. Instead if you want a healing trait Filthy Transfusion is an A+ along side Waking Dream a Resto trait that actually can go a long way healing you and your party.
Masterful Instincts is a niche pick but it can be decent if nothing else of importance is available.
For the middle rings try to always prioritize stat increasing straits and especially the ones that give you Versa, f.e. On my Way, Elemental Swirl etc.
For inner ring Impassable Visage, Resounding Protection are king, but the rest of the choices aren’t bad either.
For Essences:
For the Major slot 2 picks are prominent Vision of Perfection and Anima.
Vision of Perfection is my go to since it can give me an insane amount of EarthWarden procs during a dungeon run, boosts my damage in both aoe and st fights, and it also lowers my major defensive cooldowns.
For Minors, things are more diverse and interchangeable. My go to are Conflict and Strife and Null Dynamo. Versa is king as mentioned on the stat section and Bears have problems with magic damage so Null helps them with that.
If you are a dungeon with mostly physical damage like Freehold you can go for Strife and Aegis of the Deep or if you need more self reliable kiting you can go for Sphere of Suppression.
For Trinkets:
Since I assume you will be running M+ content only and you wont have access to Raid trinkets, your best choices IMHO are Lustrous Golden Plumage from King’s Rest and Harlan’s Loaded Dice from Freehold.
