@cso7777 How some spotting has been implemented in the past has been wrong.
BF3/4 over top, BF1 almost had it right but BFV was dead wrong.
You can have limited spotting but remove all together will weaken team communication and recon class.
Q spot everyone(bf3) - never
Q spot narrow - informing others hell yes.
Passive(ADS) local - fine (not passed to anyone)
Passive(ADS) long range(bf4) - no way
Hitting spot(bf1) - youself only maybe.
As for sensor gadgets none should be 3d (Bf4) but 2d only. Visual gadgets 3d only no 2d.
