I like Demo. Lots of neat toys, flavor-wise it’s interesting as well.
Demo is very underrated imo
Nightblade for me. a lot of versatility just like the arcanist wich is my second.
The problem with Demolitionist is that Flashbang, granado, Thermite mine and Canister bomb are very similair skills. Fire strike is good tho!
Shaman ftw
Adore Savagery <3
I love the concept of Inquisitor, and it’s dual class possibilities. But mostly, pairing it with a Demo for the Fireworks.
Thanks, Crate!
Also, for the best Necro in all ARPGS! 
I will vote for Shaman.
1 - It’s a melee mastery that works well by itself, with skills of focused damage and skills of area damage. You can also add the pets into the mix.
2 - It’s a class that combines well with other melee masteries, with caster masteries and with pet masteries.
3 - While we don’t have a Barbarian mastery, the Warder is the closer we can get from this.
My second favourite mastery is the Soldier, by the same reasons as above. Downside: no cool lightning. 
In my opinion, all classes are cool and create interesting combinations. It’s very hard to choose between them. But Shaman and Soldier are very clear to me as my favourite.
Poll appears to be much more stable now. Necro is still ahead, but it’s not a bad thing. It’s a pretty badass addition to the game
Soldier because I love shields
I voted necro. I feel like it has everything I would want for it.
>demo is in last place
Occultist hands down - love from the first sight.
Definitely could use buffs
Oh absolutely, but flavorwise what the fuck is cooler than “You cast spells? I CAST BOMBS AND BULLETS AND I HAVE A PERPETUALLY-PISSED GOD OF FIRE WHO LOVES WHAT I DO.” in Grim Dawn?
Basically a “My stare alone is enough to drive you mad God”
Bumpity bump for 2018
Disclaimer: I’m a pretty causal player (I have no chars above lvl 85 yet), so take everything I say with a grain of salt.
I think that Masteries are excellently designed, both in regards to balance and thematically. Due to the latter, Occultist wins for me. The whole idea is so magnificently Victorianesquely cool, and I think it really captures the essence of Grim Dawn universe. Which doesn’t mean more Chaos damage support would hurt!
Necromancer is also pretty good. I’m not interested in the pet part, but cold, vitality and aether themes in the mastery are very, very good. I don’t think acid/poison was necessary, to be honest. That damage type is covered well in the Occultist, and maybe it would make more sense to sprinkle it a little over the Shaman skill tree.
For people asking for Witcher as the new mastery, how would that be different from Occultist?
And, whenever I do think about possible new masteries, I find it hard to come up with something, Crate has done an excellent job in designing them.
Soldier - goes great with everything
Demolitionist - Fire!
Nightblade - Stabby Stabby
Arcanist - Abracaeverything is dead
Inquisitor - Guns 'n Frost Traps 2018 Cairn World Tour
Necromancer - Dont like pets but the other stuff is cool
Occultist - Ehh not really in my go to list
Shaman - Also not one I’ve really been able to get into. Fun to level, not so much fun in the late game.
Demo Bonus: 
Medierra said he wanted a slingshot mastery during one of the streams
Never thought pet builds were so popular.
I use to like demolitionist a lot. But with Forgotten gods on the way , and for some reason Inquisitor became my favorite:p
I need more than just an arbitrarily picked class name to like a mastery.
