maybe it's too much work or would fill the screen too much but itd be pretty cool if you could ping or let your teammates know you are looking for a specific weapon. Just a thought
As long as they limit the amount of things someone can ping to a very low number sure, I've lost count of how many games I've played where someone kept asking for stuff throughout the entire match even though they didn't really need it, or those special little * who spam the 'enemy sighted' ping across the map for no god damn reason
