Honestly I'm more concerned about them balancing the Recon class for battle royale. The BR needs less auto spotting and more manual spotting using your own eyes. Even the sniper rifles have a built in target detector now, when at least in BF4 it took up an attachment slot.
The recon drone is way too strong in terms of it capabilities. It can drop a bomb on enemies, self destruct, can be used in every fight, and when you want to enter a new part of the map can clear/spot entire area's. Not to mention it's even worse when the enemy team has more than one player playing the recon class, which means they can just alternate drone usage or combo them together.
The motion sensor can lock down entire buildings, and again with multiple recon players they can just alternate usage or drop multiple sensors to expand player "spotting" coverage.
When using a sniper rifle "off-class" it results in weapon sway, but a recon player using a "off-class" weapon does not result in weapon sway. They can combo a sniper/smg or sniper/lmg and because they have no penalty they're basically good at every range (close/med/long).
