Ok I will tell you the bug or what I think may be a bug.
First of all, just adding 1 crystal gold affix 225% plus greed 25% and fortune 20 maxes out gold too quickly if I use fortune bringer with hirling. In the previous patch, it should be 3 crystal gold affixes, 3 greeds and 3 epic affixes and more to max out gold find to 650% using the averaging formula : gf/luck 1300% /2= 650% gf/luck (850% if your using fortunate).
For the luck, it is similar situation except luck stops at 775%. For me to change that 775% to 850%, I have to add a luck epic affix and 3 luck natures on my aftermath hirling because adding 6 luck on fortune bringer isnt raising 775% at all. It just stays at 775% luck unless I sacrificed dps slots for luck affixes. In the previous patch, it should have been less than 850% luck considering that using the averaging forumla, it would be nowhere near 850% without an extra 2 crystal luck affixes in 2.0.
Secondly, for me to get max item drops I have to add 3 item drops 50% affixes on both characters because if I add all 6 on fortune bringer, it doesn’t count. That is definitely a bug. In the patch 2.0, 6 item drops affixes legend version on fortune bringer would work but it doesn’t unfortunately. This picture of adventure page is the result of two builds:
This picture supports my evidence and so you won’t think I am crazy telling facts out of thin air.
Now another thing that has been bugging me is that all the affixes on fortune bringer doesn’t count towards me if I use the aftermath wizard as the main character and fortune bringer as hirling. That must be a bug because it definitely wasn’t like this before the patch. This next picture is the evidence that I am not just being crazy and making stuff up:
I hope you understand @Refia , @Steigerbox , @Skaul , @Teacup and others who know how the averaging forumla should have worked before this patch. @cronos4321 informed me that this is a bug that must be reported and even he experienced the bug since he is the owner of fortune bringer. The bug had made the fortune bringer far simpler to make which shouldn’t be possible because it defies that formula.
