For sure! Just to start off with, if you want a powerful build, definitely build something else lol. This is definitely usable but it is not especially strong because of the lack of supporting buffs in the paragon tree and the lack of interactions with the rest of Druid’s kit. I started it for this season because of the extra power and wanted to see if it was fun and how far it would go:
Companions as primary damage dealers (goal met)
Strong enough to do most content (goal met) ~ Abbatoir of Zir is doubful from what I hear?
Originally it was all human but Blood Howl does make a wolf blink into appearance for a second.
Skills:
Blood Howl (Crit chance aspect) - Wolves (Werewolf aspect) - Poison Creeper - Ravens - Hurricane - Earth Spike (slow on hit aspect)
Despite being a “pet build”, this is an active build that relies on you to smash a lot of randomly glowing buttons and actually do stuff like pre-buff yourself. Once you get used to setting up a lot of crit you can be running through a crowd smashing poison creeper over and over or doing repeat wolf attacks.
I’m doing Metamorphosis, Sanguine Brace, Coven’s Fangs, Hectic and Ravenous
The rest of my aspects are the usual stuff to multiply damage like "extra damage based on how much resource you have, etc.
Key passive: Earthen Might
Companion builds revolve around resetting the cooldown by getting Pack Leader procs from the Wolf spirit boon. This resets all companion cooldowns with “Lucky Hit: up to a 20% chance on critical hit to reset the cooldown of your companion skills”
You want this to go off as much as possible. I’ve tried just stacking a lot of CDR and also using Hectic from the powers from this season, they do both help but the Pack Leader boon does the most work in getting companion skills available to use again by far.
The high crit chance helps both getting Pack Leader procs naturally as well as giving Earthen Might a higher chance to proc when you get crits, crits feed crits, then crits feed Pack Leader 
Hurricane is there to apply a wide area crowd control so everything nearby is automatically prepped for the Coven’s Fangs pet damage buff
Earth Spike is like rank 1 and I just use it to fish for procs and get Crowd Control for the pet damage boost outside of Hurricane (am using “Earth skills apply slow” on boots)
I have the companion damage boost on my amulet, I’ve been experimenting between using 1H weapons with a totem accessory and a 2H to figure out which one is better and I am sort of liking the 1H more because the faster attack speed as well as the extra crit and lucky hit you can get on the totem making a noticeable difference in the number of procs, but 2H has been good for a better damage multiplier too.
The biggest problem is being level 75 and literally having zero legendary nodes that are really helpful.
I’m still tweaking it to see if I can squeeze another multiplier in from somewhere to help.
Barrier (x) damage is something I want to maybe revisit. I tried the build with Bulwark instead of Blood Howl and Nature’s Fury instead of Earthen Might and it’s also effective but I’d only get the massive cooldown reduction from Symbiotic procs on either Hurricane or Bulwark from spamming one of the basics.
Honestly probably just taking off Hurricane and putting on a Core would open up some paragon options, although I don’t know if you’re building a pet build at that point?
What didn’t work was trying to rely on massive basic attack spam to reset cooldowns in a split second like with a puncture / trap rogue.
I’m not a math nerd but I am kind of looking at the Storm’s Companion pants I’ve tried and they don’t feel like they’re worth using compared to getting a multiplier. The storm wolves are also so awesome that I wear these for helltides and blood harvest because everything is paper anyways.
I’m level 82 with it now, Varshan / Grigoire / Beast etc are no problem, Helltides and Blood Harvest are extremely easy, Nightmare might be playable to like +20 monster level or so… Going to level up a bit more and then do Duriel, expecting its fine… Kill speeds on the bosses are low for me right now but not so low i’m getting bored at all.
Basically still experimenting with squeezing out more DPS by getting another multiplier or two. There’s a little bit of room to grow by using more glyph nodes too I guess.
I don’t regret making it at all. This build is probably only going to literally work for this one season and then be totally unviable in a few months unless companions get some love, so it’s a one time experience right now.
