Build for stalking your enemies that you can adjust to your liking. With how heavily the game's balancing caters to teamfights, I'd say that the most effective build is barely having any spirit items and heavily invest into gun damage and fire rate. There are still situations when if you fail to snowball, spirit invest in general can still do a lot.
