Your first purchase should be tech priests. They should constantly be up. The amount they generate is substantial.

Your upgrades carry over to the next waves. Stop racking up points in waves 1-5. With the above tech priests being up you can upgrade cadians all the way, upgrade turrets, and have a pocket dreadnaught.

Dreadnaught has a cooldown, be a good teammate and dont call it out on the first wave of a set. You get 5 minutes and its best saved for the bosses, especially against chaos.

TLDR: Stop being stupid.
