I noticed that Main Hand Damage (MHD) values do not always appear to correctly calculate / display on the hover-over tooltips when previewing the effects for your equipment.
For example – I am using Massare 2H axe; it does 78-183 Physical (PHYS), at 1.57 Attacks Per Second (APS). My base MHD is shown as 602-1143.
When hovering over Blessed Steel (BS) component, the Sacred Strike skill has the following line: 350% Main Hand Damage (1358-2255). That is not with any calculation 350% of my MHD. Instead, it is between 225% on the low end to 197% on the high end.
In contrast, when hovering over Blessed Whetstone (BW) component, the Behead skill have the following line: 280% Main Hand Damage (1685-3200). That is almost perfectly 280% of my MHD, being between 279.90% and 279.97% on the low and high ends, respectively.
To me, this looks like a bug, as I cannot see any logical reason for the mismatch, especially with such simple math. The BS component should show that it deals significantly more base damage, being between 2107-4001 damage, compared to the BW damage range of 1685-3200. Whether that is true in the real world or not, it seems the tooltip should reflect the proper values for their percentage-based Granted Skill damage ranges.
If there is something I am missing that prevents this bug from being accurate, feel free to close the report. However, if that is the case, I would argue there is something flawed with the way tooltip damage is displayed to the end user, and perhaps there should be appropriate adjustments made to the tooltips.
