Ping system: being able to ping enemies, areas, supplies.
Previous weapon swap for keyboard/mouse: would love to be able to swap back and forth between my two most used weapons by pressing a key like “q”.
In-game voice chat: I use discord, but would be nice to have mic support in game.
Optimization: I have a GTX 1080 and i7-8600k and I’m only getting 70fps. Game could use some optimization with graphics and a bit more polish.
What kind of pong do you expect from an area? 
I think the game looks REALLY good, I simply love the visuals. When the sun comes up over the archipelago? Gorgeous.
Plus it is open world with far visibility. Might explain your relatively low fps. You might need to turn graphics down a notch.
EDIT: Afaik, you can learn a skill to ping/mark enemies for your teammates. Together with other skills it even increases your damage or xp.
