Yeah I've noticed this recently, killer queues are getting longer and survivor ones slightly shorter. Maybe more people are playing killer now? We can always hope so.

Crossplay would improve this if there were console people who wanted to play with pc people because it would definitely need an opt in/out mode like with windows store/steam currently.

There seems to be an influx of new killers. We're seeing lots of red rank survivors against weaker lower ranked killers so the high rank ones must be leaving while the low rank ones are filling the void.
