"Spot enemies at objectives using Recon gadgets"

A couple things I've observed while working on this horrible challenge.

1. It only works if you spot the enemy inside the very small cap/flag area.
2. If your gadget spots the enemy before they get inside the outlined objective area and the ememy proceeds to move inside the objective area it will NOT count. Even if the spot on them goes away and they move inside the objective and then you spot them again, it will still NOT count.

The way this challenge is designed encourages counter-productive teamplay.

The prox sensor and tugs on the objective often spots the enemy before they are inside the objective area and that invalidates it. Same thing happens with the recon drone. As you are flying over it will often spot the enemy automatically before they enter the objective area making that enemy no longer valid for spot credit later.

I actually look up at the sky with my recon done as I approach the objective area to prevent it from spotting the enemy before they are inside the lines. Then only when I'm right over objective area I look towards the enemies.
