Sandstorm is pretty big on phys damage and I used it a lot in Artificer dungeon. Tangling shot seemed useless, glaive sweep too. In Lore, 5 points for glaive throw is apparently enough. For passives in Warfare, all are pretty good choices. Got some points in rapid fire, but should have ignored it. I've ignored everything but CD and VH in Warfare.
Right now using VH for bosses, does a nice chunk of damage after putting CD on them. Click to expand.I used shotguns for large groups but am now letting cursed daggers quickly poison them, almost as good as hailstorm for trash mobs, although maxed venomous hail should do pretty much the same thing.
