It was literally a simple, quick question of "oh hey, is this legendary known to be worthwhile for a Witch Doctor?" that I posted before going to bed. I didn't sit and stew intensely over providing all relevant information as well as ensuring that my question was up to the standards and regulations of the official Diablo 3 thread of critical analysis. I expected someone to go, "naa, its pretty shitty" or "oh man! Its actually great if you use X passive or get Y other legendary!"
Didn't expect such an event out of asking if a damn item is good or not...
For the record, here is my WD: http://us.battle.net/d3/en/profile/robotzombie-1891/hero/37336276
I know I'm currently inefficient and need better equips, and could definitely adjust my skills and had asked previously and gotten some good advice. But at the moment all I wanted to know was if a certain legendary was known to be good or not and I got someone calling my question ridiculous and people telling me to start putting together spreadsheets to calculate stuff..
Putting your question aside for a moment, because I don't have one, I would suggest trying to see if there's anything you could drop to fit in Grave Injustice. Maybe switch to Wrathful Protector Gargantuan (which should go with the Fire theme) and drop Midnight Feast for GI? You'll lose the +50%, but WP Garg should still vastly outperform Big Stinker, and Grave Injustice should allow you to have him up ~80%+ of the time.
