I have 2 black weapons, a 1118 dps EF and 900 dps butcher sickle. A witching hour belt dropped for me few days ago with 50CHD and 8IAS. I have about 38-39% crit chance, the tooltip said I will gain 2k dps if i switch my inna's belt with this Witching Hour. However when I did switch it, I lost 5k dps on sheet.
What I'm wondering is, I guess the +X% Holy damage doesn't get calculated on the tooltip, but it gets calculated on the sheet dps? So does that mean if you have a Witching hour and 2 black weapons with high dps but you have lower than 40-45% crit chance, you will gain DPS by switching to Inna's belt?
