If you block Chuppe/Grava with skellies or totems on the balcony, they provide one hell of performance . 
Actually in my “experience” small Communities for let’s say an more “niche” Game compared to competitors tend in general to feel / be more friendly than others. Mean if you have like 2 millions unit sold with 100 People actively on an Forum where 1% is toxic, and than compare it to an Game which sold 30million units and 1% is toxic the difference is pretty obvious… even more due in my experience it’s easier to meet toxic people online (for more popular Games / Mainstream Titles) than People who enjoy the Game. Also Forums like this aren’t the mass appeal anymore compared to the “old days” nowdays it’s either Steam-Forums or Social Networks, i guess GD Steam-Forum you will more toxic people than here.
True, social media platforms are a growing area for players to get together. The Steam forum is a bit more salty than here at times, but Zantai/Steam mods are pretty quick to deal with any reported problems. GD Discord can get bad occasionally too, but again mods/admin step on things pretty quickly. Can’t comment on other social media stuff since I don’t use them.
Some of it could also have to do with other games being competitive ones. People looking to brag/denigrate others wouldn’t make for a friendly and welcoming community vibe.
Forum state represents the state of the game.
Look at PoE forums - they’re full of rancid jerks, and that game is flawed likewise.
Also you shouldn’t forget about rebellous people who dislike Games which are popular / mainstream or is an “threat” / “competitor” for their own game… a.k.a. haters. If i remember back on the Diablo 3 i’ve quite often saw PoE topics / (or even GD) Fanbois who hate on Diablo 3 and spread toxic atmopshere…
/edit:
Though i have to point out, that even in nice communities like Grim Dawn, can have toxic behavior / topics / atmosphere if there are topics which are outside of their bubble and talk about competitors. I don’t want to talk in an Sony Forum about Xbox or Nintendo-Switch, nor here talk about other HnS like Diablo 3, TL2 or so, because i know (from experiences) that most collectives begin to trashtalk…
Yes, there is that too, but hopefully most contributing members here will temper their replies and if not then a moderator will step in.
As for badmouthing other games well, I think that falls under the “respect the ideas of others even if you disagree with them” guideline. I’m not a fan of PoE, but lots of people are; I wouldn’t touch any Diablo game, but millions of people love them. Different games for different gamers.
I see no point in comparing Grim Dawn to other games,opinions are based on personal taste.I usually don’t write in forums,but after reading some threads,decide to make reg and I like general atmosphere and the fact you can receive valuable help and suggestions.Every game is some kind of competition,but in GD as single player game you can play at your own tempo and style and that creates uniqueness.
Value of valuable has been qusetionable as far as the builds went so far. e.g. AA builds didn’t really work until high levels, many skills were near-worthless without hard to farm gear or full sets (And writing for posterity). A newbie who went to the build compendium would have found it to be mostly useless. (For the majority of AoM’s lifetime). Beginner/Budget builds (G1-2) rarely cropped out from the woodwork. Most mastery combinations lacked and still lack budget builds.
Still, the community is friendly, is helpful, is pointing out imbalances, Zantai fixes a lot of them, and sometimes spectacularly so (see the 1.0.6 soiled pants buff), the Mythical Wyrmbone Mask which was for a long time the way to mock demolitionist threads because it converted 100% of forcewave, but not stun jacks, was fixed. We have 100% phys to lightning conversion for mortar trap. We’re getting 100% phys to fire in FG. The formulas.gst bug was finally fixed (Thanks Rhys).
And Zantai has a knack for pulling the venom teeth out of a discussion that’s going astray. See the pre-1.1 demolitionist threads back in december/january.
Mythical Will of Bysmiel 
So… that is how the forums became so friendly?
Mythical Will of Bysmiel?
And now that it has been nerfed?
For the sake of the friendliness of the forums, Buff Will of Bysmiel, Devs!
No. That is what the forums became friendly DESPITE of. But yeah, the edit should better explain this.
As for Mythical Will of Bysmiel (MWOB), voidfiends when?
