I want to compile a list of all prefixes and suffixes that are missing post-U19. The devs have said if we notice a prefix or suffix missing that was around pre-U19 to bug report it. This is difficult to do as some prefixes and suffixes have been rolled into others and some are more rare than others. For example, bane weapons are no longer around by design. Undead Bane has been rolled into Ghostbane, Construct Bane has been rolled into Smiting, etc., so do not report those. If you have noticed a prefix or suffix that you are fairly certain is missing, report it here and I will do some investigation and then add it to the list. When I get what I consider to be a fairly complete list, I will post a bug report template for people to do quick and easy bug reports. Let's tell the devs we want our affixes back!
Please note which prefixes and suffixes you have noticed have gone missing. A list of clothing and jewelry affixes can be found here. A list of weapon affixes can be found here. A list of rare weapon affixes can be found here. A list of armor affixes can be found here. A list of the enhancements added in Update 14 (Menace of the Underdark) can be found here. If someone can summarize where to find rare armor/shield and clothing/jewelry enhancements can be found, a link would be appreciated.
