Found an clever glitch with the MAV on metro level on Conquest.
If you start as the team on the outside, you can fly the MAV through the roof of the subway tunnel, and just plonk it on one of the roof rafters (enemy can't see it due to the glitch) and coin the points in.
Plus it helps your team by showing up the attackers.
Best position is in the roof above the escalator or last flag.
you need to fly along the far right street and then fly into the roof (looks black smoke through the MAV cam)
