For the Legacy nats out there:
here is an infinite rapid fire build for you:
works best with a slower weapon. around 1.6 to 1.8 aps
then Rapid fire and refill with punishment
Resummoning ur turrets or casting punishment will not break channeling.
**Castin gloom before u channel RF will keep the healing and dmg reduction as long as u keep channeling.**
It is MP10 viable =D
this may work as well for non-legacy folks if u have enough crit chance just replace archery with nightstalker or:
Enjoy and happy 1.08!!
