Ive tried many bow builds. With the current heavy meta i have found this works well in ganking or group.

Wood elf nightblade. 561 cp

5 spraggan
5 widowmaker
1 kra'gh

Double poison and stam reducer poison.

Stam/crit and brutality poton

Food is health and stam regen


Bow bar
Lethal arrow
Poison injection
Ambush
Killers blade
Piercing mark

Second bar
Vigor
Dark cloak
Charging manuever
Radiant light
Shuffle

Back bar is buff or escape so while attacking i never need to switch bars.

Gank or small scale stay at range and pick off players. If larger zerg battle stay in front line and chase or dodge roll back if in trouble

Most fun is keep defense or attack. You can pick off players with ease on or below walls.

Once you understand timing and spells, drop poison arrow and take venom arrow. The stun is awesome against rezzers and casters.
