For those with a physical copy from 2003, 1.27b was annoying. It was part of Blizzard's slow roll toward the eventual Reforged launcher. The patch removed the ability to play via "CD crack" or the old school disc check. You now needed a valid CD key tied to a Battle.net account. While this killed piracy, it also meant that if you lost your jewel case from high school, your copy was toast.
The headline feature of Patch 1.27b (and the 1.27a update that preceded it) was the removal of the CD-ROM check.
In 2016, asking players to keep a physical disc in their optical drive was not only archaic—it was becoming impossible. Many modern gaming laptops don't even have disc drives anymore. By removing the DRM requirement, Blizzard effectively future-proofed the game for digital play.
However, this created a small dilemma for purists. The patch changed the main menu screen from the classic aesthetic to the ladder map selection screen. It was a small price to pay for the convenience of launching the game without a disc.
