[2019] Build suggestions

Hello all. Just moved up to WT1 and I was wondering if their are some suggestions about successful builds out there. I think I am leaning towards a SMG/LMG build because if the total ammo/clip size and RPM. As well, I want to load up on Offensive Damage icons instead of Defensive and skill power

I am not sure if this is the best idea to do in the endgame. I am open to any and all suggestions and critics to my ideas.

Also, what gear traits do you think would be best for me?
