Firstly, remember that you can change the builds if you believe you need to, like if you're against a Nova / Zeratul then maybe Spell Shield would be important, and in similar fashion Stoneskin / Blood for Blood could be taken to have more sustain & utility in fights.

Mutishot build functions best if you can't get very close to fights without having the risk of being picked off

Hungering Arrow build allows for good burst along with ample mobility to dodge skill shots.

Finally the Auto Attack build will be most popular since the multishot nerf, it decimates tanks and does a good job on objectives (even structures!).
