Attack speed from weapon is not being added in detail area. Changed weapons and no difference. This happened when toon went from seasonal to norm.
Not a bug.
Attack speed of weapon (IAS) is included in Attack Per Second (APS) on the sheet. e.g. a normal weapon has 1.4 APS, with 7% IAS, it becomes 1.5 APS.
Attack speed increase (ASI) are additive and appear separately on the sheet.
Please refer to ASI and IAS in this wiki:
