Suggestion Com Marker usable on map
I think there is an issue with LOS, given that their patch notes said they fixed a bug that was having object markers persist once no one in the squad could see them. What you might want instead is an additional function where you can mark the map and have the mark show up on the squad members’ maps but not out in the world, beyond the base blue star personal point.
I don’t think the design is childish, by the way. I think it is elegant. The rough shape of the symbols match the painterly aesthetic of the game, and the variety of shapes are meant to be clearly different from each other so even colorblind players can distinguish them, as explained on the live stream that revealed squad markers. A great deal of careful thought went into the symbols and how to blend them into the game while keeping them distinctive.
If they were cartoon kitten heads with little tongues sticking out (like the tattoo “options” in BnS creation) then I’d agree they were childish.
