Exactly.
Even in the Blizzard post justifying the use of 1.12 AV, they stated:
It’s just not a reasonable argument from anyone and that includes Blizzard. The justification doesn’t apply to the year 2019 with 1.12 classes and items. I wish people would stop arguing based on their experience and memories from 2005, and instead used logic; maybe we’d get Blizzard to recognize their folly.
The best argument for an earlier recreation of AV is to quote Blizzard’s own justification for their use of patch 1.12: “After careful consideration, we decided on Patch 1.12: Drums of War as our foundation, because it represents the most complete version of the classic experience.”
The version of AV they chose does not represent the most complete version of AV. It’s a trimmed down version with less content.
