They're not doing anything like that now. They're replicating it but they said they're going to stick with patch 1.12 and that means a lot of spells and weapons will act differently in Molten Core than originally. Back then spells and abilities changed nearly every patch, like a Paladin's Seal of Command was originally based on 100% weapon damage but by 1.12 they changed it to 70% but added Judgement. Also Libram's didn't drop until around 1.12 as well. Them not replicating patches is just lazy on their end.Because they'd need to backport over a decade of security/exploit patches and changes to their baseline infrastructure?
