DS makes me tunnel more than not
I main Nurse and have a very slug-centered gamestyle. My rule of thumb is to go into the games (with 0 slow down perks or sloppy butcher, at most) and slug and hook people, actively avoiding tunnel (if I have more options than just the person who got unhooked, I'll take them). I will make sure to hook everyone somewhere between 1-2 times before it htis 2 gens and then I'll look to kill someone finally (as this slows the game down to a halt and usually means I'll get 3-4 kills by the end, but the enemy team can at least feel like they've played the game).
However, I'll run across people who sit on top of gens or run into lockers to force DS. I understand that this might be to prevent slugging. But I will 100% tunnel someone out of the game after they use that perk on me (unless it was my own doing of picking someone up before 1 min. is up). I feel like this is such a dirty way to use the perk and once it is gone, I can just abuse that fact (instead of being forced to assume that everyone runs it).
