First match and it’s started

Some people will always tunnel. No matter what you do.

Sure and if that doesn't work out somehow for the killer, they just resort to the tried and true method of tunnel out for the 3v1.

That sure would be bad...if that's how that actually worked and you weren't making things up.

It's not a 26 second block on every gen in the game. It's a 12 second block on every gen and 26 seconds on every gen that was being worked on at the time of the grim trigger.

Also the combo is incredibly easy to play around, after the hook if it's the person's first hook just wait a few seconds after the hook and if no Grim trigger you're fine and if grim trigger just wait the 12 seconds and it's done and then no DMS trigger. It's not like Eruption because you could never know when a person was going to go down with Eruption. This it's very simply just wait 5 seconds after someone's first hook. You know exactly when it could happen and how long to wait, you had neither of that with Eruption.

1. Getting hooked twice in a row is considered tunneling.
2. Defending last gens is now harder because of gen regression events.
3. Events are not impactful. Gen regression perks are the same. If you mean 5% regression perk kick instead of 2.5%, then it's 3 seconds of gen repair. It's extremely easy to do, especially if 2 or more survivors do that. As long as you don't try to do that in killer's face, stopping gen regression is not much of an issue.
4. Where exactly does a killer without very specific perks have a comeback mechanic?

1. If you double-hook someone and then ignore them for the rest of the match until you've gotten a solid number of hooks on others, they're really not going to care.
2. This is actually pretty doubtful. How many games do you actually manage to rack up eight regression events on one gen, without also winning that match? Besides, your job isn't to keep the gens from being done.
3. YOU think they're not impactful. That's a difference.
4. Who said anything about a comeback -mechanism-? The game's built from the ground up to work that way. The killer starts behind and can overtake the survivors. The game doesn't hand it to you, but you can easily secure extra kills even if the early game was trash. If the survivors had a bad start, it's incredibly difficult for them to recover.

1. But you do realize that survivor who was double hooked already is in the risk of being hooked for the third time at any moment and has to play safe? It's not like killer will intentionally ignore a survivor who is repairing a gen in front of it, right? Being double hooked like that means you can get eliminated the moment killer finds that convenient or required.
2. That's the thing - in this gen block meta, you likely don't get those 8 gen regression events because you rely on getting gens blocked long enough to get survivors eliminated. Go for gen regression perks and chances are you will eventually get a gen that can't be manually damaged by a killer anymore.
3. Maybe it is a subjective thing here. If so, then this entire point is irrelevant.
4. Who decides that killer starts behind at all in the first place? Killer spawns in one point of the map and survivors somewhere else ( provided no offerings are used ). It all goes about luck whenever killer finds and does catch survivor off-guard and gets early downs or hooks or has to spend time before any chase does happen and lose a gen while searching for the first target. There's absolutely no guarantee at any point of the game that one side will win or lose. Odds of winning or losing do change based on how many survivors are still in the game and how many generators were repaired.

Which is about when that survivor is released from the hook again. That's the problem with tunnelling. An issue you don't have with gens.

It's not a gen-block meta thing. BHVR chose 8 because it was a number that, according to their statistics, is barely ever hit -outside- of 60-min stall tactics. You're very unlikely to hit this limit, so long as you don't play exclusively for gen defense.

That's how the game progresses. Your first chase has the most pallets in it, and the least pressure on survivors. Your later chases will have more pressure on survivors, fewer pallets, people might be injured, your power might come online, whatever you may have, but generally speaking, killers start the match at their weakest. Which is why it's unreasonable to point to the very first chase as some kind of indicator for the rest of the game. Plenty of matches where the first hook comes at three gens done still result in a 3K+.

Conversely though, if a survivor is dead and there's more than one gen left to do, the chances of a 2E or better are infinitesimal.

Killers can make comebacks pretty easily. For survivors, it's almost impossible. That's why this focus on a 'fair' early game is entirely unreasonable.

1. The relation of tunneling to gen is that getting someone tunneled out asap is the best gen regression tool for a killer out there. Less survivors left - slower the gens may get repaired.
2. Gen block meta is about defending gens from being completed, is that not? You sacrifice gen regression but in exchange you don't spend gen regression events. A simple example here is having a gen being blocked for you for 30 seconds or having a killer come and do a kick and regress a gen to it's 30 seconds before state.
3. Absolutely subjective and random experience. Your first chase may be the easiest one where you catch survivor off-guard and get a down in first 10 - 15 seconds in the game against a chase at later where survivor loops you around the shack or jungle-gym or circles around 2 pallets forcing you mind game or tank the pallet. Game result can change at any point of the game because there are plenty of other factors, such as survivor altruism or greed or killer's relentless pursue of the weak link or mere mass slugging.
4. Even if there are 3 survivors and 2 gens left, chances of escaping still exist so long as gens are decently spread, there are enough pallets and survivors are capable of keeping killer busy. This part is about luck and skill, which can be the biggest variable. Saying that killers can make a comeback and survivors can't is a bit of a short-sight, when there are so many factors that need to be considered. Perhaps since killer is alone, this so-called comeback is more noticeable because survivors are about a team work and coordination where killer is about making right decision at the right moment.
