The radar is truly garbage. Walking, running firing portal doesn't ping a player. It makes engaging feel like rng and, ypu could just be walking around and, someone that spawn behind you wipe ypur whole team. Feels bad yo have you 10-15 kill streak wiped because, someone spawned behind ypu and, you couldn't do anything about it because, there is no ping. Halo did it right, your crouch and, sacrifice some mobility to go off radar or you can choose to keep your mobility but, stay on radar.
