I want to downgrade my version of StarCraft II. Some arcade games I used to play haven’t been working since huge patches like 2.0.0 or 3.0.0. I believe there is no official way to make them compatible on the latest patch. Is it okay to play on old patches, and if so, how can I do it? Right now, I can only think of download WoL 1.0.0 and applying all the incremental patches one by one.
