If you're complaining about tunneling and camping while you and your team allow the killer to do it, maybe it's time to reflect on your own gameplay instead of blaming the killer. Improving your game sense and looping skills would go a long way. If you can't manage that, maybe consider playing with friends in SWF or customs, where you can coordinate better. Either you improve and give the killer fewer chances to tunnel and camp, or you help your team by actually playing smart instead of just complaining. At the end of the day, these are viable strategies, and if you can't counter them, the issue isn't with the killer—it's with you.
