Classic is still a big part of the new game and I always missed having a classic specific leaderboard in D2:LoD. I finished variables needed to put together classic category. To run classic all you need to do is enable "Pre-Expansion" on character creation.

In classic the goal is to kill normal or hell Diablo. Timer ends when Diablo dies. Classic only supports Amazon, Necromancer, Barbarian, Paladin and Sorceress. I've added these 5 as separate Classic Class variables.

You're not allowed to convert the character to Expansion during the run or it won't qualify as a classic speedrun.
