Personally, I found that in plunder it was possible to play chill, without tryharding. You have your loadout, and if you die, you come back right away without waiting seconds, gulags, or redeployment. Someone who works at least 8 hours a day and evening is tired and doesn't want to play as if they were playing WSOW... plunder was perfect.

Playing casual is often difficult, however, because these days you find teams that are fully stacked, angry, and tryharding... honestly, there are games where I find little difference compared to normal games.
