To clear up acouple things.. We are not limiting the good team to 2 gokus, and 9 total players(for example), teh whole good team can be goku. Also, we will not use evil skin, they look uber ***...
The scouter displays the location of the people around you, if you aim it on someone, it shows their Name, character, and powerlevel. Also, if someone is holding a dragonball, they will blink Orange and then Red/Green(depending if hes on your team or not).
Last but least the arrow over the other players heads cannot be removed, unless you go in the sprite dir and do some h4x0ring... But trust me, you want it enabled, almost impossible to see people far away from you.
