other good huntsman skills:
Ballistic shot - hits like a truck at long range.
Marksmans fang - ignores physical armor, and hits multiple targets in a line
Assassination - the rangers version of backstab, fun talent if your a sneaky type.
Arrow Spray - powerful ability (costly too). particularly potent at close range against mobs with a large hitbox. It's a room clearer.
Other alternative skill lines:
Summoning - does not rely on Int for damage, so perfect for a ranger type. fits the RP mold too (ranger with pet buddy, etc.)
Hydro - heal spells and magic armor buffs are golden.
Aero - 2 points for the teleport skill. don't need much more.
Pyro - haste spell can be particularly effective.
Geo - like Hydro but for physical armor.
