Chieftan Lead Sprinkler help.

Hey guys. I can't find many guides that go into in depth detail on building a Chieftan Molten Strike/Lead Sprinkler. I have been following Lifters guide as best I can. I was curious if you guys could take a look at my character Alteredwrath and see what specifics I should upgrade on my build. Thanks a ton. I'm hoping it will still be all content viable once I am done.
