It’s gone. Face it. Blizzard launched WarCraft 3: Reforged and replaced everyone’s classic version of the game with a 30GB abomination, and it isn’t coming back. At least, it doesn’t seem that way from the latest official post. There’s talk of updating all versions of the game (even those that didn’t buy Reforged) to include leaderboards and clans, and a quick bit about custom games, but it’s a done deal.
“We want to say we’re sorry to those of you who didn’t have the experience you wanted.”
Don’t even ask about the EULA changes that give Blizzard the rights to your creations.
