I'm playing helltooth, other than having shit luck with weapons, it wrecks.
Pet builds are kinda dead, no real reason to run garg for anything other than early 70 gearing and dogs can be kinda useful at times and actually aren't too bad now with chilled to the bone but still you eventually replace them. You do run fetishes in helltooth though, with the belt of transcendance, permanent army of fetishes for basically free, they tank stuff and shit so it's nice and for farming easier stuff they activate Fierce Loyalty movement speed buff. Zuni's still good for Carnevil which is actually competitive if you have all the items, but Helltooth is just a lot easier to setup since you don't need every single piece, you can build over time, while Carnevil is pure garbage until you have at the very least dagger of darts and carnevil, and it's pretty bad until you have SMK/Jeram/6pc Zuni on top of it. Meanwhile Helltooth 2pc can carry you close to T6 on its own.
Arachyr 2pc is great too when you start gearing up, the spider does a ton of damage on static targets(aka bosses and shit). The rest of the set is kinda meh, even with Majuma or the firebat bracers, especially the whole having toad of hugeness up all the time where he gobbles elites and shit so you can't damage them for a while.
Oh and talking about ramah gifts, I got not one, not two, not even three but FOUR today. Dat RNG. Still waiting on a furnace or ancient Suwong/Scrimshaw though. Or even just a good ancient at all. All the ones I get are poop.
