Ameesha & [Itzal] are great and all but they lend little function besides a taxi between objectives when used in Plains of Eidolon, Forutna and The Cambeian Drift

Elytron is the unsung hero of the Open Word.
It is a solid air-to-ground attack tank.
Just as fast flight
Actual useful utilities

The 1st ability Bloomer takes quick care of airborne units.
The 2nd ability should be used when the "projective approaching" warning appears and the threat is ceased almost instantly
Use the 3rd ability to clear pesky spawns of mother trash automatically as you fly
The 4th ability can deal some serious AoE dmg to clear the ground for a strategic landing.
It also is very useful in clearing breakable objects such as plants and crates so that you can swoop by in the arcwing or use your companion fetch/[Vacuum] on the ground to collect your riches.
This by way the most efficient way to farm those type of resources
