"We don't want to mess up the Mona Lisa" - Blizzard may expand Diablo 2 even more if the surprise warlock class release goes down well

Surprise: Blizzard shadow-dropped a Warlock — Diablo II's first new class in 25 years — as part of the paid Reign of the Warlock expansion. If players love it, Blizzard may expand D2 more, while keeping a preserved classic. #Diablo #Warlock
