I've had loads of fun with this build this league. You can literally swap on any Bow or Crossbow skill, use it as your one-button primary attack, and destroy the game.

This build makes ANYTHING work... including even skills like Ice Shards, Shockburst Arrow, or Rain of Arrows, as a one-button clear all build.

Didn't get a chance to record video of all skills as there are just so many and it all takes time.

My favourite skills to use with this build (as a primary one-button build based on fun + effectiveness) ranked in order:

1. Machine Gun (Armour Piercing Rounds)

2. Galvanic Shards

3. Crossbow Shot

4. Siege Cascade

5. Poisonburst Arrow

6. Ice Shards

7. Rain of Arrows

8. Rapid Shot (+ Explosive Grenade)

9. Glacial Bolt

10. Siege Ballista

11. Gas Arrow

12. Gas Grenade (with Mortar Cannon)

13. Shockburst Rounds

.. everything else dunno.. about the same, less fun for me or less effective.

Cluster Grenade (with Mortar Cannon), Oil Grenade (with Mortar Cannon), Lightning Arrow, Spiral Volley, Artillery Ballista, Ice Shot, Permafrost Bolts, Incendiary Shot, Fragmentation Rounds, Explosive Grenade, Explosive Shot, High Velocity Rounds.
