Allow a feature of bonfire next to beaches where people can park their car with some friends and have a conversation, toast or anything.
Lately, it have not been feeling as a community festival and rather a bland experience. UK in FH4 had a cozy vibe which players enjoyed. Mexico fails at providing the cozy vibe, unless you introduce features like bonfire on the beach, volcano, etc. and community building.
It might take some work but mostly it will be a great addition. This kind of feature is already there in some other multiplayer games, so a serene car meet with bonfire will be fresh and vibrant. Please put some thought into it.
World is not changing in mechanics. This is a fairly static change.
