Tracker's cores and alfa dog recon skill is absolutely useless.
I don't know about PC but on Android and iOS we have a pace , speed and rof at which such skills do not have time to work. Similar to the radar built into the shield commander, also six sense core . The enemy will kill you before you take advantage of it.
Opponent is too fast and these skills do not work.
Too many skill, cores for up speed now.
Every one move like Supersonic or Roadrunner.
Every night I take my tambourine and sing songs specially for the medic. "May luck accompany him always and everywhere"
