My view is two builds on this. One for damage with siege bombs, other is protection.

For damage 4 points need to be in barrage, canon skill.
Throw 5 30 -60
Long volley 5 60-120
Siege 5 450 -900

Or something more like this with still good damage in siege. I am deciding to try something like this on the guy I am on now, one more level in grenades.

Throw 1
Long volley 5
Explosive 1
Stink pot 1
Fire bomb 1
Smoke bomb 1
Siege 5
Determination 1
Demolitions 0
Toughness 5
Ignore pain 5

P.S. Probably least favorite skill, and almost ends up always being last one completed, even though now I use them through the entire build of other skills.
