Killer-sided map according to him. So noob skill issue for not taking advantage of how confusing the map layout is for that poor SWF team.
It's usually the same with popular games. The top streamer tends to be someone who usually is at a pretty high level, but almost never top level. Top level is intimidating, high level makes the audience feel like "Oh yeah, I can do that." Many examples in many games over the years, of course, I'm sure everyone can think of a few.
Streaming as a whole is pozzed as fuck. It's too good a marketing tool to ignore and not curate. And simultaneously, it is too massified to not pick and choose those who rise to the top on the part of companies. There is just no way in fuck Otzdarva's 8 thousand viewers make as little noise as they do just thanks to the glory that is Slow Mode. 65-70% of Twitch's userbase are streamers trying to make it. There's hundreds of thousands of 1-0 viewer channels out there. No joke, many of these dudes are way more skillful than Otzdarva could ever hope to be.
In the end, it's almost always one guy who is harmless enough, advertiser friendly enough and average looking and acting enough that makes it and gets hailed as the lord and savior of a specific community, often for no particular reason, which is Otz's case here. Success seems arbitrary a lot of the time, which is why a lot of people keep toiling on that streaming wheel endlessly, hoping they can get lucky too.
Of course Otz is under a lot of scrutiny from better players, because his word carries more weight than anyone's. A lot of people resent this, because Otz is basically a combination Voice of The Scrub Legion/Corpo Shill who's ultimate objective is not the health of the game, but to keep the gravy train rolling as long as possible. Not helped by how he's constantly babied by Bhvr and put in lower MMRs where he can go on relentless seal clubbing sessions. Of course, this is the sort of thing Bhvr wants to make the game look like. It's all about the narrative. Gen grabs are fun. Simple mindgames are as well, when they work. High level DBD looks and feels like an absolute fucking mess. It's loop patiently around the pallet for a set number of laps until the survivor drops it, then the killer tries to get away with some bullshit like dropping chase or a mindgame and the survivor tries to counter it with flowcharts. Fuck up your threegen patrol even ONCE as killer and you're already dead, specially if they brought their bullshit "Don't care, just get genrushed" perks like Potential Energy or BNPs. Clip channels are also cherypicked to high heaven from the aforementioned sealclubbing sessions, and without context or deeper game knowledge, you'd think guys like Otz or JRM are god gamers, and while they are above average, they are certainly not that impressive. This makes gauging the reality of the game's balance impossible to most of the playerbase.
Case in point, his latest takes sound so retarded they might as well be disingenuous: The new maps are cancer for killers. Shelter Woods has a literal infinite window loop in the main tent. Temple of Purgation looks dumb as fuck with clashing green tones in a mostly grey, late winter forest. And as Bruno said, it's just super easy to break LOS now. But then again, I've seen people, people who play DBD every day, just walk up to Cuntmerchant's drones, tripping the wire, and just waiting there to disable the bot while getting exposed and revealed. I don't think most of the community is even at a level where they read tooltips, so they are just as likely to take Otzdarva's word as gospel. It's the same sort of PR and damage control League of Legends used to run. For that game, it was pretty effective. I'd say Killer mains in general do read and theorycraft more often, but Survivor mains are your everyday MOBA soloQ bot.
After that, you get Otz playing The Thot Merchant with his gifted by bhvr thot skin, and he wins a lot and brings attention to this (She's probably not that weak, you guys!) Then as soon as he loses one he fucks off from Killer Q until his Bhvr monkey can tank and lock his MMR so he can pick on scrubs endlessly again for the next stream. When most of the playerbase can't even be fucked to read a tooltip and cook up some basic-ass counterplay, this is probably gonna be pretty effective at swaying opinion. Meanwhile, the dude who's completely cracked the mistery to playing Blight and is able to do crazy 180-then-bounce flicks and get absolutely impossible hits everywhere is sitting around Youtube with 300 subscribers in virtual obscurity because he's just not camera friendly enough and prefers to make edgy mid 2000s AMV montages. For most games nowadays, high profile streaming is more about being marketable and positive than about being really good at the game. Of course, this doesn't apply to every single game out there, in fighting games 9 top streamers out of 10 are gonna be extremely good and the 10th is gonna be a surprisingly good woman... But when Yakuza's venerable developer Sega makes the call to throw in streamers and other celebs, they call wrestler Kenny Omega and Vtuber Nyanners, not neckbeard devilleon7 even though he is easily the best known Western Yakuza streamer, and they definitely are NOT ringing up any of the No Damage autismos. And that's when they're not getting some pornstars to feature.
TL;DR Otzdarva is something of a really high profile shill but his opinions have to be taken with a mountain of salt, primarily because he's clearly getting notes from corporate in what and what not to say, and DBD as a whole is just the right mix of busted, wonky and obscure enough that most of the true top tier stuff in the game, which is just borderline cheating, 99% of the community is never even going to know about, much less be able to apply.
