BFV devs said that there will not be shared weapons among classes (except pistol and melee weapons). Still how would you feel if bolt-action rifles(e.g. kar98k,Lee Enfield ) are available for all classes, but only Recon/Sniper class has access to optics? So they would be appropriate faction locked, no optics of whatsoever, just plain ironsights for Assault, Medic class. Maybe for Support class as well.
