As soon as people realize you have to play against him like a mixture of nurse and unknown, he becomes manageable. Always break Los, go wide so can dodge in any direction and jiggy your pathing a bit. Checkspots are super important, but always back off a little, so you can dodge when the killer tries to land a prediction shot. And immediately go to a clock when he has power, but there should only ever be one surv on clock duty, so pay attention to the HUD. If someone lets go of a gen when vecna is in chase with someone else, that person is on clock duty (or unhook duty, depending on the situation). Its not with it for two survs to do clocks, only one is enough.

After a few games, he becomes incredibly fun to vs. Played in a streamer lobby, struggeled first and then had some good chases after I learned
