Guide
For Emblems you want max white and 2 browns, and 2 or more purples/blues, you also want to have as much HP and defenses as possible. The assault vest is only used for extra hp and bulk and can be removed if necessary. You want to get early kills and score early to evolve and then tank everything.
This is how I got to master class, enjoy =)
