How does the loot from warzones 4, 5, 6 work?

Question

I got a question about loot from war zones 4, 5, 6 - how does it work? Is the drop 100% random or is it like for example Ghaz'haragoth, player who dealt the highest damage gets the best loot?

Answer 1

It's 100% random, also the same item can drop multiple times for multiple people.
