Let other squad leaders see different squad leaders pings in different colors. Red for alpha, blue for bravo, green for charlie, etc. It'd help squad leaders know what squad has what point tagged. Your squads marker remains light blue.
I think the markers should just have a subtle letter of the squad somewhere. The other colors should be good for warlords, however. If they actually make it in someday.
We could use small letters and these colors: Limit the amount of squads per team to 12 and use: Primarys for Alfa, Beta and Charlie. Secondarys for Delta, Echo and Foxtrot. Tertiarys for Golf, Hotel, India, Juliett, Kilo and Lima. I also suggest the symbol to be split in the different colors for squads with the same order.
But then 8% of people are color blind. That's about 56 players on peak atm... Mb we just need to see all other squad marks as slightly less intensive shade than ours? That way we make sure that all objectives are getting attention.
