The Banshee Steal in AotCR is a literal godsend for speedrunners, and much easier to pull off than the series of cliff jumps that dominated speedruns of this level in the past. Note this only works on Heroic and Legendary, as no Banshee appears on Easy or Normal.
Here's how it works:
Switch to Classic graphics. As you exit the door quickly take out the Grunts on either side, if any, and plasma nade the left shade turret to flip it off into the abyss. Position your character in approximately the same spot as I do in the video (push the camera down as far as it will go and align your reticle with the line on the ground). The Banshee will make its way toward you. Just before the Banshee's right wing crosses the dividing plane in the mountains behind it, crouch for around one second. If done correctly, the Banshee will veer into the wall behind you. As it makes contact with the wall move to the left side of the door, hugging its surface. Once the Banshee passes above the door, cross to your right just below the Banshee. If your timing is right, the Elite will hop out and the Banshee will drop to the ground in front of you, allowing you to fly through the rest of the mission without any more enemies spawning.
Note that while this exploit is generally easier to pull off than the cliff jumps of yore, it's no walk in the park and will likely take dozens of attempts before you have the timing, positioning, etc. down pat. One of the more common mistakes is crouching too early or too late. The window here is critical for the Banshee to follow the path it needs to take for the exploit to work. Too early and the Banshee will bank left instead of continuing around toward you, too late and the Banshee will track you too long and crash into the geometry in front of you. Good luck!
