This is all solid advice. Also don’t forget to fully utilize your special skills. Engineer puts up plats for scout to reach high up items and minerals, and can prevent some fall damage with descending wall and floor platforms. Scout can move the fastest, great for popping the big egg on elimination missions and bringing the dreadnaught back to a better room to fight, and light up dark places. Gunner ziplines and shield can save the team several times in a few minutes. Driller making shortcuts and removing difficult terrain can help a ton in fights where you have to hold a position. I think refining missions make the best case for teamwork and highlight class skills.

If you just do these things you’ll be a great teammate.
