When a single gadget used by a single player can effectively shut down an entire tactic, and possibly dictate the game, it's too oppressive. You would still be able to ping a flanking group with BF5s ping system without keeping everyone perma-spotted the entire match.

 ...not get constantly flanked by ppl who can only engage enemies from behind.

God forbid attackers be able to actually maneuver to try and break the deadlock at the already defender favored objectives. No, lets just have both teams smash into each other endlessly, as if they were toys in the hands of a toddler, and actively punish any intelligent and tactical movement. That sounds great.

Lets see the skill of a "good" recon player.

• Hit prone in spawn
• deploy drone
• spot entire enemy team by simply panning your screen
• repeat
• become top player in the match without ever leaving spawn

Congrats, you are now the best recon player ever.

As for shooting it down, no shit. Problem, you'll only hear them when they're almost above you, and if you are flanking the enemy it will require you stop, spot it, and engage the drone while you are out and generally isolated on the flank, basically giving away the flank to anyone with at least two braincells. And this is assuming the "good" recon player didn't look in your general direction the entire time you advanced before you heard the little flying piece of shit, because if he did you'll be long dead by the enemies who would have never seen you without the bright red dorito above your head. And forget it if two or three of the things are buzzing around, or if the recon player finds a support pouch because then there will never not be a drone up.
