Campain playing the unbuffed hard version

Hello!

After watching GGG’s warcraft 3 retrospective I wanted to replay the campaign, and found out the hard version in the reign of chaos had been made harder in reforged.

However, after I started playing the human campaign I realised all the missions are playing at the pre “buffed” version, and doesn’t match the versions I have seen others play. For example kelthuzad still just has a few abombs and low health in Andorhal. I know that I am playing on hard as the blademaster in mission 2 was lvl 6 and used bladestorm, though that isn’t the issue.

Did they reverse these changes and I missed it, or am I having some sort of bug?
