Problem as I see this - the sniper spotting device - requires nothing - you place it somewhere and then it just spots everything in sight. If you are spotted - it is very easy to see you. If you are on a team where not many use this - then you have problems. Snipers on rooftops and place those spotters everywhere - then its hopeless. Next thing compared to BF 2042 - here we also had spot things all over - but here all classes could take smoke nades and run in smoke. In BF 6 only support can have this - unless you have the 320 nade launcher unlocked and pick smoke in that one. I cannot recall the very old BF 3 and 4 - I know here you could also place this spotting device and leave it - but unsure if it was only for vehicles or also people. In BF 6 it requires manual work (push of trigger) to lock / paint the target with this thing - meant for javelins - stingers and so on.
And also remove aim assist - has nothing to do in any game - unless in campaign - but should never be in any multiplayer !
