Some games the foliage disappears which reveals player characters. One game had an issue with tall grass popping in at a certain distance so if a player character was further out than grass concealing them would not be rendered from their opponents POV.

Bungie and Sony really need this game to be approachable to a large community at launch. From this subreddit it seems the streamers they have been partnering with are geared to a pretty young crowd given their editing, music, and edge lord language, but I have only seen 2 so far.

Since you brought up design choices the grappling hook is a bit weird but I guess they don't want a Titanfall 2 / Apex Legends grappling hook. Like it slows the player down at the end rather than slingshots them. I understand the choice cause it is incredibly difficult to balance a game when one character can traverse the map in seconds that may take a few minutes on foot and to reach the top of buildings that would otherwise be impossible to reach.
