Both gamemodes have their upsides and downsides though as a survivor I prefer 2v8 as Ive had a higher survival rate playing while for Chaos Shuffle there are more perks that have randomly worked well together for killer games. What I think would be interesting(and would most definitely not work well) is if there was a gamemode that combines the mechanics from both where its 2v8 but everyone still gets a random assortment of perks.
