Oh my god I love that third one Visibility has never been a problem in games, if you have nothing physical between you you can always see them or a name tag It'd be something new to have darkness/rain actually be an issue Maybe they could incorporate flares? Or orbs to place so you can see in a certain area? In a cold night, out hunting far from the tower, cold could be an issue. Visor frosting up Decreased movement Maybe increasing damage as it reaches extremes I really like this BUNGIE PLEASE HEAR US
