Archwing Leveling

[Atekron]

I did almost reach MR 24, and except couple zaws, saryn, nekros, and 2 or 3 kubrows I did level-up all stuf, except archwing and archwing weapons.

I would be really thankful for all advices and tips of where and how to do it more quickly and painlessly

Find someone who has the latest archwing (can't remember the name), and go to salacia, the mobile defense archwing mission (on nepture or uranus, can't remember).

Or just pick that archwing yourself.

You don't NEED it, but it makes the mission impossible to fail.

 

Then just smash everything because in mobile defense enemies never stop spawning and you'll get plenty of exp. Even better if you're playing elytron or with someone who has it.

Just don't forget to kill with the gears you want to levelup.
