My Feelings on "Camping" and "Tunneling"
I always try to avoid these tactics as I understand survivors find them toxic and I can agree that it's not fun if the killer sticks by you and chases you off the hook. But I think that a lot of people let their own subjective experiences get in the way of their own objective evaluations. I'll constantly come by people who attempt to derail them as legitimate and legal strategies simply because they don't enjoy them. It's the same with the "gen rush." The main difference between the concepts is that gen rushing is a byproduct of a genuine flaw in the game's core design, (however still legitimate and legal in and of itself), whereas, camping and tunneling are not.
Now, a lot of the time, I feel like camping hurts the killer as you surrender all pressure, but if the killer knows you're an overly altruistic team, or the exit gates are powered, why wouldn't they stick around when you're essentially giving them free pressure? It's the same with tunneling: It can be the more efficient move. If I'm not already in a chase, or I am and I see you get unhooked, why wouldn't I switch to you if you're one hook closer to death? One hook closer to that 3v1. Personally, I have no problem if the killer signals me out and/or camps me because I get that that's how they've decided to play and depending on their situation, it might be the smarter move. I also have no problem if survivors do gens really fast because what else is there for them to do really?
TL;DR, at the end of the day, both survivors and killers will play how they want to play. It's pointless to try and control that reality. Try to get past that and enjoy the game or move on.
I'm curious on your's guys' thoughts.
