90% reviews, while before the patch the game would range on the 80% ish due to bugs

Crazy numbers. Tbh i didn't encounter any engine bugs (crashes, etc) in the D2 v1.01, except some quest logic issues, where you can't complete some quests or open some chests.
An, ofc, stupid game protection.

Patch 1.02 more like an expansion of features than a bug fixes. Actually, the whole changelog tells nothing about which bugs were fixed (well, there is mentioned only some crashes produced by "fading" - ??? - system).
